2.1.4 SEM : Technical Specification
1.0 The energy metering system specified herein is used for tariff metering for
bulk, inter-utility power flows, in different Regions of India. One static type
composite meter is installed for each EHV circuit, as a self-contained device for
measurement of active energy (MWh) transmittals in each successive 15 minute
block and certain other functions, as described in the following paragraphs.
2.0 The meters is suitable for being connected directly to voltage transformers
(VTs) having a rated secondary line-to-line voltage of 110V, and to current
transformers (CTs) having a rated secondary current of 1 A (model-A) or 5A
(model-B). Any further transformers/transactions/transducers required for
their functioning is in-built in the meters. Necessary isolation and/or
suppression is also be built-in, for protecting the meters from surges and
voltage spikes that occur in the VT and CT circuits of extra high voltage
switchyards. The reference frequency is 50Hz.
3.0 The active energy (Wh) measurement is carried out on 3-phase, 4-wire
principle, with an accuracy as per class 0.2 S of IEC-62053-22:2003. In
model-A (for CT secondary rating 1A), the energy is computed directly in CT
and VT secondary quantities, and indicated in watt-hours. The meter
computes the net active energy (Wh) sent out from the substation bus bars
during each successive 15-minutes block, and stores it in its memory along
with plus/minus sign. It also displays on demand the net Wh sent out during
the previous 15-minute block, with a minus sign if there is net Wh export.
4.0 Further, the meter continuously integrates and display on demand the net
cumulative active energy sent out from the substation bus bars upto that time.
The cumulative Wh reading at each midnight is stored in the meter’s memory.
The register moves backwards when active power flows back to substation
bus bars.
5.0 The meter counts the number of cycles in VT output during each successive
15-minutes block, and divides the same by 900 to arrive at the average
frequency. This is stored in the meter’s memory as a 2-digit code which is
arrived at by subtracting 49 from the average frequency, multiplying by 50
and neglecting all decimals. For example, 49.89 Hz is recorded as 44. In case
the average frequency is less than 49.0 Hz, it is recorded as 00. In case it is
51.0 Hz or higher, it is recorded as 99. The average frequency of the previous
15-minutes block is also be displayed, on demand in hertz.
11
6.0 The meter continuously computes the average of the RMS values of the three
line-to-neutral VT secondary voltages as a percentage of 63.51 V, and
displays the same on demand. The accuracy of the voltage
measurement/computation is at least 0.5%, a better accuracy such as 0.2% in
the 95-105% range being desirable.
7.0 The meter also computes the reactive power (VAR) on 3-phase, 4-wire
principle, with an accuracy as specified in clause 11.0, and integrate the
reactive energy (VARh) algebraically into two separate registers, one for the
period for which the average RMS voltage is 103.0% or higher, and the other
for the period for which the average RMS voltage is below 97.0%. The
current reactive power (VAR), with a minus sign if negative and cumulative
reactive energy (VARh) readings of the two registers is displayed on demand.
The readings of the two registers at each midnight are stored in the meter’s
memory. In model-A (for CT secondary rating of 1 A), the reactive power
and reactive energy transmittals is computed in VAR/VARh directly
calculated in CT and VT secondary quantities. When lagging reactive power
is being sent out from substation bus bars, VAR display have a plus sign or no
sign and VARh registers move forward. When reactive power flow is in the
reverse direction, VAR display have negative sign and VARh registers move
backwards.
8.0 In the model-B (for CT secondary rating of 5A), all computations, displays
and memory storage is similar except that all figures is be one fifth of the
actual Wh, VAR and VARh worked out from CT and VT secondary
quantities.
9.0 The meters are fully complying with all stipulations in IEC standards 62052-
11:2003 and 62053-22:2003, except those specifically modified by this
specification. The reference ambient temperature is 30° C.
10.0 Errors are reasonable for all power factor angles from 0° to 360°.
11.0 For reactive power (VAR) and reactive energy (VARh) measurements, IEC
62053-23:2003 complies with. The accuracy of measurement of reactive
energy is as per class 2.
12.0 Each meter have a test output device (visual) for checking the accuracy of
active energy (Wh) measurement. The preferred pulsing rate is twenty (20)
per Wh for Model-A and four(4) per Wh for model –B. It is possible to couple
this device to suitable testing equipment also.
13.0 No rounding off to the next higher last decimal is done for voltage and
frequency displays. All 15 minute Wh figures is however be rounded off to
the nearest last decimal.
12
14.0 The three line-to-neutral voltage is continuously monitored and in case any of
these falls below about 70%, a normally flashing lamp provided on meter’s
front become steady. It go off it all three voltages fall below 70%. The time
blocks in which such a voltage failure occurs/persists is recorded in the
meter’s memory. The lamp automatically resumes flashing when all VT
secondary voltages are healthy again. The two VARh registers specified in
clause 7.0 remains stay-put while VT supply is unhealthy.
15.0 The meters normally operate with the power drawn from the VT secondary
circuits. The total burden imposed by a meter for measurement and operation
is not exceeded 10 VA on any of the phases. An automatic backup for
continued operation of the meter’s calendar-clock, and for retaining all data
stored in its memory, is provided through a long-life battery, which is capable
of supplying the required power for at least 2 years. The meters are supplied
duly fitted with the batteries, which shall not require to be changed for atleast
10 years, as long as total VT supply interruption does not exceed two years.
The battery mounting is designed to facilitate easy battery replacement
without affecting PCB of the meter. The meters don’t require any separate
auxiliary supply for their operation. All displays may disappear on loss of VT
supply.
16.0 Each meter has a built-in calendar and clock, having an accuracy of 30
seconds per month or better. The calendar and clock are correctly set at the
manufacturer’s works. The date (year-month-day) and time (hour-min.-sec.)
are displayed on the meter front (when VT supply has been connected), on
demand. Only limited clock adjustment is possible at site, using the DCD.
When an advance or retard command is given, six subsequent time blocks is
contracted or elongated by ten seconds each. The meter does not accept
another clock correction command for seven days. All clock corrections is
registered in the meter’s memory and suitably shown on print out of collected
data.
17.0 Each meter has a unique identification code, which is marked permanently on
its front, as well as in its memory. All meters supplied to POWERGRID as
per this specification have their identification code starting with “NP”, which
shall not be used for any other supplies. “NP” is followed by a dash and a
four digit running serial number, further followed by a dash and “A” for
Model-A, and “B”, for the use with CT secondaries of 1 A and 5 A
respectively.
18.0 Each meters have at least one seven (7)-character, seven-segment electronic

21.0 The meters store all the above listed data in their memories for a period of ten
(10) days. The data older than ten (10) days get erased automatically.
22.0 Each meter has an optical port on its front for tapping all data stored in its
memory. Portable or hand held data collection devices is also be separately
14
provided for this purpose, one for each substation, to serve as the interface
between the meters specified above and the local personal computer (PC). In
addition to above each meter is provided with a RS-485 port on one of it’s
sides, from where all the data stored in the meter’s memory can also be
tapped. The overall intention is to tap the data stored in the meter’s memories
once a week from any of the two ports mentioned above and transmit the same
to a remote central computer using STD or other communication links,
through the local PC. It shall also be possible to obtain a print out (hard copy)
of all data collected from the meters, using the local PC.
23.0 The whole system is such as to provide a print out (both from the local PC,
and from remote central computer) of the following form:

unique identification codes. They are totally sealed and tamper proof, with no
possibility of any adjustment at site, except for clock correction.
26.0 The meters are safely withstanding the usual fluctuations arising during faults
etc. In particular, VT secondary voltages 115% of rated applied continuously
and 190% of rated for 3.0 seconds, and CT secondary current 150% of rated
applied continuously and 30 times of rated applied for 0.5 seconds shall not
cause any damage to or mal-operation of the meters.
27.0 The meters also withstand without any damage or mal-operation reasonable
mechanical shocks, earthquake forces, ambient temperature variations,
relative humidity etc. They have an IP-51 category dust-tight construction,
and shall be capable of satisfactory operation in an indoor, non-air conditioned
installation.
28.0 The meters continue to function for the remaining healthy phase(s), in case
one or two phases of VT supply fails. In case of a complete VT supply
failure, the computation of average frequency (as per 5.0) shall be done only
for the period during which the VT supply was available in the 15-minute
15
block. Any time block contraction or elongation for clock correction also be
duly accounted for.
29.0 The harmonics preferably be filtered out while measuring Wh, VAR and
VARh, and only fundamental frequency quantities is measured/computed.
30.0 Either the meters have built-in facility (eg. test links in their terminals) for in-
situ testing, or a separate test block is provided for each meter.

energy accounts in case any of the 'main' meters become unsuitable for the purpose.
3.2 Types of Meters
I) Interface Meter: Interface Meter is connected at the point of interconnection
with inter-state transmission system (ISTS) for the purpose of electricity accounting and
billing. Meter shall be owned by CTU.
II) Consumer Meter: Consumer meter means a meter used for accounting and
billing of electricity supplied to the consumer. Meter shall be owned by Licensee.
III) Energy Accounting Meter: Energy Accounting and Audit Meter means Meter
used for accounting of electricity to various segments of electrical system. Meter shall be
owned by generating company or Licensee.
3.3 Metering Arrangement
3.3.1 Metering arrangement for NTPC stations
Three sets of energy meter i.e. Main, Check and Stand-by energy meters are provided to
calculate the energy sent-out. One set each of Main & Check Meters is provided on all
outgoing feeders and stand-by meters are provided on the EHV side of the generator
transformer (GT) and station supply transformers
3.3.2 Metering arrangement for ICTs
For measurement of energy supply to a constituent/agency through an ICT, the Main
meter is provided on the HV side of the ICT and the Standby meter on the LV side of the
same ICT.
22
3.3.3 Metering arrangement for inter-State transmission lines.
In case of SEB-owned Inter-State transmission lines, say between State 'A' and State ‘B.',
the energy meters are provided at both the ends of the lines. The meter installed at end 'A'
is the Main meter for working out net drawal of SEB 'A' and that installed at other end 'B'
acts as check meter for SEB 'A', and vice-versa.
3.3.4 Metering arrangement for POWERGRID lines
On POWERGRID lines, unless an end is a regional energy accounting point, an Energy
Meter is provided only at one end of each line. The readings recorded by these meters are
being used for information and analysis only, and not for the energy accounting purposes.
3.4 Maintenance of Special Energy Meters
3.4.1 Testing and Calibration
All equipments are duly tested. In particular, each and every meter is being subjected to
acceptance tests as specified by CTU, at the manufacturer's works, before dispatch.
3.4.2 Periodic testing of accuracy
i) In-situ functional checking and rough testing of accuracy are being carried out for all
meters once a year by the CTU, with portable test equipment complying with IEC-60736,
for type and acceptance testing of energy meters of 1.0 class.
ii) Full testing for accuracy for every meter is being carried out by the CTU at an
accredited laboratory once every five (5) yrs.
The constituents/agencies may depute one authorized representative to witness the tests.
3.4.3 Meter Calibration
The meters normally need not to be recalibrated. However in case a meter is found to
violate any of its accuracy , functional requirements during the above periodic accuracy
checks, the same is replaced by CTU by a duly tested/certified meter, and the defective
meter is sent back to the manufacturer for appropriate recalibration and re-certification

3.6 FICTITIOUS METERS
Sometimes it is required to treat a combination of METERS as a single entity. e.g.
(i) Total drawal of an SEB
(ii) Total relief from a generating station
(iii) Total transaction of energy between two regions.
In this case, these items can be treated as just like a single meter, we call it as
FICTITIOUS METER (FICTMTRS). The following listed meters are called
FICTMTRS used to simplify the calculation process. Every fictitious meter consists
and basically summation of certain no of Real meters. Real meters are the actual
meters which are placed at different location and store the raw data. E.g.
START
01 (FK-92) M9
+(FK-08) +(FK-09) +(FK-10) +(FK-11)
+(FK-12) +(FK-13) +(FK-17) +(FK-15) +(FK-16)
………………………..
100 (RN-97) M2
+(RN-95) -(RN-96)
101 (RN-99) M1

3.8 PAIRS.DAT file
This file gives the LOC-ID of main meter and standby meter and the permitted
pair tolerance for each pair. Main meters are those which are connected on 400 kV side
of ICT or generator side of power station or sending end of inter state lines. The
standby/check meters are on the other end. Standby meters are connected in reverse
polarity so that sum of both MWh is zero in ideal condition. Suppose the power flow is
from main meter to standby meter, the main meter gives a +ve value and standby meter
gives a –ve value and vice versa. Tolerance value in MWh for a 15 min block in +ve
direction & -ve direction is given in this PAIRS.DAT, depending upon transformer /Line
loses & CT/PT errors.
The given tolerance value towards +ve side is called X value. The tolerance value
towards –ve side is called Y value.

4.0 PROCESSING & COMPUTATION OF DATA
4.1 Scheme for collection and dissemination of data
4.1.1 General
While CTU has the overall responsibility for supplying the meter data to ERLDC
on a weekly basis, the respective constituent’s agencies, in whose premises the energy
meters are installed, normally down-load the metered data from each of the meters on a
weekly basis or as and when requested by the ERLDC. The respective constituent’s
agency ensures that the data is down loaded in the specified time schedule. ERLDC, in
consultation with the constituents, prepares a scheme for the timely collection of the
metered data from each meter location and its further transmission to the ERLDC. The
constituent/agency shall also ensure the security of the metered data up to its delivery to
the ERLDC and seven days thereafter. All constituents shall provide the required
assistance/co-operation to ERLDC. Each station is also requested to keep back up of all
data systematically that are sent to ERLDC.
4.1.2 Data Collection from different location
At each metering locations data is to be collected from SEM once in a week. With
one data collecting device, data of about ten SEM can be collected sequentially and at
once dumped into PC. For dumping into PC the software given by supplier of SEM has to
be used. After downloading the metered data of seven days from each meter location, the
respective constituent’s agencies send the data normally through e-mail from specific
location to ERLDC. These data should reach ERLDC latest by Tuesday so that it doesn’t
cause any delay in processing. Special energy meters are either SECURE METERS
LIMITED (SML) or L&T Make. These raw metered data are non readable type (non
editable and naturally tamperproof). SML make meters have *.MRI or *.AMR file and
L&T make metres have *.DAT file. Since these files are non readable files, so these files
have to be converted to *.NPC file which is readable and editable. It is better to make
NPC file at RLDC to reduce human error.
63
4.1.3 Saving of Raw Data
Data after downloading attachments is saved in computer in a folder (e.g.
SEM_DATA). Since these data are in MRI or DAT file these files need conversion into
TEXT file (although some location sends NPC files along with both MRI and DAT files).
But it is better to convert MRI and DAT file into NPC file at ERLDC to reduce human
error. After converting into NPC file these are stored in a folder called as ‘READINGS’.
4.2 Conversion into Text File/Software for Data Viewing
After receiving the data, MRI file and DAT file is converted into TEXT file called NPC.
This conversion is done with the help of respective software. MRI file is converted into
NPC with the software called SMARTGRID supplied by the Manufacturers and DAT file
is converted into NPC with the help of VINCOM software.
For Secure Meter: SMARTGRID
For L&T Meter: VINCOM
A) SECURE METER (SMARTGRID Software): All mri files are
transferred to SEM_DATA folder in C: drive before converting to text file(i.e
NPC file). Following are the steps to convert mri file into text file
.Step-I : Login the SMARTGRID software after click on SMARTGRID icon on desktop.
64
Step-II: Go to Data option on menu & click to Convert for conversion of mri file into
npc file.
Step-III: Select all mri file to be converted into text file
65
After conversion mri files along with npc files are transferred into respective location
wise folder in C:\READINGS\Mmyy\....
A) L&T METER (VINCOM Software): All *.DAT files are transferred
to SEM_DATA folder in C: drive before converting to text file (i.e NPC file).
Following are the steps to convert dat file into text file.
Step-I : Login the VINCOM software after click on VINCOM icon on desktop
66
Step-II: Click on Import from Data option on menu.
Step-III: Browse button to select the file and import one selected dat file at a time.
67
Step-IV: After importing convert into text file.
68
Step V: Finally conversion takes place. And click on ok and after each import and
conversion finally close the application software.
After conversion dat files along with npc files are transferred into respective location
wise folder in C:\READINGS\Mmyy\....
4.3 Viewing of npc file/structure of npc file
(i) There is one week heading for each meter data which gives the start date and end
date for which data is available e.g.
WEEK FROM 0000 HRS OF 12-10-07 TO 1230 HRS OF 22-10-07
(ii) For every day data there is a day heading that gives METER NO, three register
readings at 0000 HRS of the day, and date of the day e.g.
NP-4201-A 63895.0 97845.8 74358.6 12-10-07
Three cumulative registers are (i) WH register (ii) VAR register at high voltage (>103%)
(iii) VAR register at low voltage (<97%).
69
METER NO is of 9 characters, usually starting with NP (e.g. NP-0139-A). Character A
or B depending upon whether the meter is with 1 AMP CT or 5 Amp CT
(iii) One day data consists of 96 blocks. Each for 15 min is organised in 6 lines e.g.
WEEK FROM 0000 HRS OF 12-10-07 TO 1230 HRS OF 22-10-07
NP-4201-A 63895.0 97845.8 74358.6 12-10-07
00 14 +11.50 00 +11.10 08 +10.89 04 +10.34 01 +10.38 00 +10.21 06
+10.56 00 +10.48 06 +10.20 11 +10.33 00 +10.05 12 +10.30 07
+10.68 02 +10.66 12 +10.65 05 +11.01
………. …….. ……….. ………….. …………………. ……………….
Each line contains 16 blocks i.e. data for 4 hours. Time is followed by 16 blocks and
starting Time is in HOURS (2 digits) is given at the start of each line. Each block
contains a frequency code and WH for the 15 min. Freq code is of 2 digits and range is
from 00 to 99.
In between frequency code and WH there may be a “*” mark if there is any voltage
problem (V<70% during any instant in the 15 min). If any correction is done during the
15 min, there may be a “aa” or “rr” corresponding to advance or retard of the clock.
There may also be a case of voltage problem and time correction occurring in the same
15 min block.
At the end of 96 blocks the algebraic SUM of WH of all block is also given. One NPC
file may consist of data for one meter or more than one meter. Data for each meter starts
with a week heading. After receiving the data from all locations for a week, they can be
combined to make a complete file for the week. A program APPEND.EXE is given for
that purpose.
4.4 Modification/Editing in Text file
After conversion into Text file (NPC file) every file is renamed as ddmm.NPC
where dd and mm correspond to the week for which data is being processed. Also extra
70
meter readings to be deleted from the text file which is not required and if some
correction of date etc is required it is done in the text file and saved into corresponding
folder from where data have been received. These are normally saved in folder named as
“READINGS”.
4.5 Availability Checking
This is done to ensure whether data from all location has received or not. This is
checked by running software called REA2006 and we check for location from where data
has received or not received, if the data has not received, then the concerned agency or
person is contacted telephonically to send the data.
4.6 Methods used in case of Non availability of data
In case of non availability of data from any location, there are different alternative
methods to evaluate the data.
I. If Main meter reading is not available then check meter reading is used as
substitute for any particular location in FICTMTRS.CFG file.
II. Another alternative is to use other end data in case of non availability of data.
III. There is another approach to evaluate data by applying Kirchhof’s law at BUS
from where data is not available but this approach is not always valid..
Sometimes data are sent from different location by email attachment but required
proper data is not found in attachment. In that case the concerned agency or person is
asked to resend the data again.
4.7 Final Processing
APPEND.EXE simply combines all *.NPC files starting with the same “ddmm”.
The combined file name is ddmmSREA.NPC. It is better to make a single file
“ddmmSREA.NPC” which includes all the data for one week. This can be given as the
input to the data processing program. (REA2006 at the create DATA base option) This
total file can be stored easily as a back up file also.
71
MASTER FREQUENCY METER:
It is an special energy meter whose recorded frequency code is used as standard freq code
and is used for region, NR. ER, WR and NER ( NEW Grid) and the constituent within
the above mentioned Region for any calculation such as Unscheduled interchange (UI)
etc. This meter is installed at Korba (WR) end of Korba-Vindhyanchal line. Meter No is
NP-2465-A. This meter recorded data is sent by WRLDC to every other RLDC weekly.
Durgapur meter NP-6461-A is used as back up Master Freq Meter in case any block ,any
day or any week data is not available at Korba end installed Master Freq Meter due to
any reason such as opening of line or Meter Failure etc.
REA 2006
(i) REA 2006 processes the text file (NPC file) of SEM (special energy meter) for
completeness, correctness and computation. NPC file may contain Data for a few
METERS or ALL METERS in the region (ddmmSREA.NPC) which obtained
using append program for a few days (usually 9 days).
(ii) The program takes special care to check the data at every stage. The NPC file is
first checked for syntax correctness. Then creating a database by splitting the data
into day wise and meter wise files, so that further processing is easier.
(iii) Various checks can be carried out on the data to check both data validity and
strength of the meter to record data properly.
(iv) Energy in MWH and MVARH is computed from WH and VARH using
corresponding CTR and PTRs. Wherever a pair is available (e.g. 400 KV and 220
kV side of ICT) computed energy is compared and data correction is done,
accordingly (for “*” marked blocks). Load curve can be plotted if required,
Drawal, share and overdrawal/underdrawal are computed using the FICTMTRS
(fictitious meters) concept.
(v) Output file can be made as desired by the user by making appropriate
configuration file.
72
(vi) Option is made available to change the freq code tolerance (temporarily) for
frequency analysis and to modify temporarily each pairs to get approximate pairs
tolerance value for analysis of each pair.
Following are the activities before creating data base.
First it is checked for the location from where data has not been received. If data is not
received from some location then it is asked to send the data. After receiving all the data
from each and every location, again all NPC file is combined together by
APPEND.EXE command and SREA file is created. After that it is gone through data
correctness stage. If status is not found ok then corresponding data file is edited that has
caused the error. Then Data base is created.
So finally by running REA2006 software we go through final processing with the
following steps.
I. Location of data not received
II. Data Correctness
III. Create Data base
IV. Compute ENERGY
V. Compute FICTMTRS
VI. MWH output
After creation of data base ENERGY is computed (compute ENERGY option) and
computation of FICTMTRS is done for the seven days of the corresponding week. After
that MWH output is calculated for the week. With the above steps the constituent’s Net
Drawl, Regions Net drawl and ISGS Net Generation, etc for the week is calculated.
Regional loss is calculated after adding total bilateral of the week in net central sector
generation. Details of FICTIOUS METERS used for computation of Net injection as well
Net drawl is shown in Annexure-B.
73
4.8 Data check and its validation
By data checking and its validation we go through to verify or cross check that
whether meter is recording data correctly or not. So by going through all check files ie.
MWH output files, it is observed for any mismatch or discrepancies.
Following are the check files:
A. Net bus check of Substations
These provide the net bus of all important substations in the Region. In case any
discrepancies it is noted and observed.
B. Net bus check of Generators
These file gives the net bus of ISGS of the Region. In case any discrepancies it is noted
and observed.
C. Pair- Check (End to End)
By going through these pairs file we observe and check for any mismatch at the two ends
of transmission lines. It is investigated for any deviation other than tolerance value.
So Identification on metering error can be done broadly through three categories of check
files as mentioned.
I) Net Bus of Sub- Stations
II) Net Bus of ISGS
III) Pair Check of end to end
4.9 Discrepancies
If there is any discrepancy in the week’s data processing, it is listed out in register
for every week and these are used during final processing of data. These discrepancies
are forwarded to ERPC (Eastern Regional Power Committee) along with Raw and
processed data. These discrepancies are also uploaded on ERLDC web along with ISGS
injection and Constituent’s drawl.
74
4..10 Data forwarding to ERPC
Processed data of the week along with raw data and discrepancies is forwarded to
Eastern regional Power committee (ERPC). Contents of the data which is forwarded to
ERPC are:
1) Raw data of each location
2) Constituent wise processed data
3) Processed MWH data
4) Day wise meter data
5) Configuration file of the week
6) Discrepancies, if any
7) Any other information, if required
4.11 Uploading of data on ERLDC web
Constituent wise net drawl and central sector Net generation along with region
loss and discrepancies if any, is uploaded on the ERLDC web site (http://www.erldc.org)
for the concerned week. Weekly UI calculations are being done by ERPC. As requested
by constituents, processed meter data as per calculations of ERLDC are being uploaded
just for the sake of gross comparison only.
75
4.12 Data Archives
A data archive for processed data along with raw data of every week is
maintained on PC to take care of any future dispute. Back up for Data Archive is also
maintained either on CD or Hard disc. The data archive structure is as follows:
Meter Archive
