2.1.4 SEM : Technical Specification

1.0 The energy metering system specified herein is used for tariff metering forbulk, inter-utility power flows, in different Regions of India. One static typecomposite 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 currenttransformers (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 andvoltage 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-wireprinciple, 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 CTand 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 alongwith plus/minus sign. It also displays on demand the net Wh sent out duringthe 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 netcumulative active energy sent out from the substation bus bars upto that time.

The cumulative Wh reading at each midnight is stored in the meters memory.

The register moves backwards when active power flows back to substationbus bars.

5.0 The meter counts the number of cycles in VT output during each successive15-minutes block, and divides the same by 900 to arrive at the averagefrequency. This is stored in the meters 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 casethe 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.


12/102

11

6.0 The meter continuously computes the average of the RMS values of the threeline-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-wireprinciple, with an accuracy as specified in clause 11.0, and integrate thereactive 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%. Thecurrent 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 meters

memory. In model-A (for CT secondary rating of 1 A), the reactive powerand 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 nosign 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, displaysand memory storage is similar except that all figures is be one fifth of theactual 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 thisspecification. 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, IEC62053-23:2003 complies with. The accuracy of measurement of reactiveenergy is as per class 2.

12.0 Each meter have a test output device (visual) for checking the accuracy ofactive 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 couplethis device to suitable testing equipment also.

13.0 No rounding off to the next higher last decimal is done for voltage andfrequency displays. All 15 minute Wh figures is however be rounded off to

the nearest last decimal.

14.0 The three line-to-neutral voltage is continuously monitored and in case any ofthese falls below about 70%, a normally flashing lamp provided on meters

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

meters memory. The lamp automatically resumes flashing when all VTsecondary 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 secondarycircuits. The total burden imposed by a meter for measurement and operation

is not exceeded 10 VA on any of the phases. An automatic backup forcontinued operation of the meters 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 atleast10 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 dont require any separateauxiliary 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 30seconds per month or better. The calendar and clock are correctly set at the

manufacturers 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 isregistered in the meters memory and suitably shown on print out of collected

data.

17.0 Each meter has a unique identification code, which is marked permanently onits front, as well as in its memory. All meters supplied to POWERGRID asper 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

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.

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 CalibrationThe 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 actualmeters 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

(RN-95)*3.8/100
