Section 4: Functional DescriptionIntroductionThe DP-300 is a three-phase current differential protection relayfor generators, motors, and transformers in block connection (pro-tected object). The currents flowing in the individual conductorsare each measured using a current transformer on both sides ofthe protected object. They form the protection area boundary orzone. All two- or three-phase short-circuits and line-to-earth faultswithin this protection area are detected by the DP-300 as faultcurrents which cause tripping. The unit does not trip if fault cur-rents occur outside the protection area. In this way, a selectiveprotection is guaranteed.All six measuring currents are electrically isolated. The unit calcu-lates the differential current and restraint current internally foreach phase separately. The following settings are taken intoaccount for this:

Transformer vector group; Rated current of the protection object on the low-voltage side; Rated primary current of the current transformer on the high

and low-voltage side; and Voltage transformation of the transformer.

During the calculation, the star connections on the windings arearithmetically converted into delta layouts to eliminate the zero-sequence system. The different relationships between the currenttransformer ratios and the voltage transformation can lead to rela-tively different currents even when there are no faults. In order tomanage defined ratios, the measured value on the high-voltageside is standardized so that it can be compared with the measuredvalue on the low-voltage side. The reference side is the low-volt-age side; therefore the configured rated current on the low-voltageside must be referred to. It is recommended that the generatorrated current be used as the reference value for unit connections.

Note: The measured values of the differential protection are shown as per-centage values related to the configured rated current.

The unit monitors six measured currents via isolated inputs. Theunit calculates internally the restraint current (I s ) and the differen-tial current (I d) separately for each phase. The actual values ofthe calculated parameters (differential current I d and restraint cur-

rent I S) are shown on the display either as absolute values or as apercentage of the generator rated current (selectable in lockedinput mode).Theoretically, the currents I a and I b are equal, both in fault-freeoperation and outside the protection zone (Figure 6-A). The differ-ence is zero and the differential protection does not initiate. How-ever, in practice, current differentials do occur (= spuriouscurrents), even in fault-free operation. They result, for example,from summation or phase angle errors in the CTs, which are influ-enced by deviating burden values. These spurious currents remainsmall inside the operating range, but increase with increasing loadand are especially high when one or more CTs become saturated(e.g. in the case of an external short circuit). In order to prevent atripping of the relay due to spurious currents, the trigger thresholdis not held statically constant but increases in relation to therestraint current I s . Spurious currents need to be taken into

account when adjusting the trip characteristic.When a fault occurs inside the protection area (Figure 6-B),unequal currents flow in the CTs, which result in a current differ-ential. If this exceeds the differential protection threshold, therelay will trip.The circuit diagram in Figure 6 serves to explain the protectionconcept for in-phase and equal currents. The differential currentand restraint currents are determined arithmetically.

Measurement InputsThe unit records six current values for the current differential pro-tection.For differential current measurement, the unit forms the sum oftwo values (restraint current I S) and the deviation (differential cur-rent I d). The actual value of the values determined (differentialcurrent I d and restraint current I S) is shown as a percentage onthe display with reference to the rated current.

Differential Current MonitoringThe monitoring of the differential current is carried out in twostages.The first monitoring stage serves as a warning and can be enabledor disabled. Should the adjustable warning characteristic beexceeded, a text appears in the display and a relay contact isenabled. The pick-up time and the dropout delay of the relay out-put are adjustable. The warning stage of the monitoring is auto-resetting.The second stage of monitoring (main stage) serves to initiatetripping. In contrast to the first stage, it offers the possibility tomonitor the overstepping of an adjustable tripping characteristic

(Id < I n) and additionally, a fixed tripping-threshold of 100%, rel-ative to the generator rated current (I d > I n). The trigger-delayfor each limit value may be independently adjusted, thus allowinga shorter triggering time at higher differential currents. When oneor both tripping characteristics are exceeded, a text display is ini-tiated and two relay contacts are energized. The tripping charac-teristics possess a 2% hysteresis relative to the generator ratedcurrent.The signal relay is only automatically reset if the function "auto-acknowledge relay" in the Entry field on the screen is configuredto "ON". Otherwise, the resetting is carried out by pressing the"Clear" button on the front of the unit or via the discrete input ter-minal 18 "Reset".

Tripping CharacteristicThe Figure 7 shows the tripping and warning characteristics (withsample values for X12, Y1,and Y2). It represents the tripping andwarning thresholds (Y) relative to the restraint current (X). Thecoordinates P (X12/Y2) and P (X12/Y1) are the positions of thecorner points. The selection of these positions is dependent onthe generator being protected. The following gives the ranges oftripping and warning thresholds:

IS / I N 0 to X12 The threshold I d is independent of therestraint current.

IS / I N X12 to 5 I N The threshold I d is dependent on therestraint current. A change of 100% inthe restraint current causes an increaseof 10% in the tripping threshold.

IS / I N > 5 I N The threshold I d stays constant at 85%.

Different characteristics can be chosen for the first and second

monitoring levels, whereby the horizontal position (X-coordinate)is valid for both stages. The vertical position (Y-coordinate) canbe chosen separately for each monitoring level. This results in afixed difference in thresholds of the first and second monitoringlevels for each restraint current I S .The unit can measure currents up to 5 I N accurately. Depend-ing on the vector group there can be a deviation in measuring thedifferent currents and the unit can trip. The message "rangeexceeded" is displayed when tripping due to these currentsoccurs. Currents larger than 5 I N will only result in tripping if ashort circuit is within the protected area. If the short circuit is out-side the protection area, only the generator would be drive thecurrents measured by the CTs.

Electrical Restraint of Inrush Current and Overexcitation withTransformersCertain transformer operational conditions can cause differentialcurrents without there actually being a fault present at the pro-tected object. This includes energizing the transformer and oper-ating in overexcitation mode. When a transformer is energized, a

current inrush flows in on one side which can be variably highdepending on the instantaneous value of the supply current. If along high-voltage line has a transformer at the end that is beingenergized, overvoltages can occur and overexcite the transformer,inducing increased currents on one side. As the currents onlyflow one-sided in both cases, a differential current will be mea-sured which results in false tripping.During an inrush current, there are typically high proportions of2nd order harmonics present. However, during overexcitation,there are predominantly 5th order harmonics present. The har-monics component is determined in the DP-300 using the digitalFourier transformation (= DFT) and this is used as the criteria forelectrical restraint against false tripping.To activate the electrical restraint of an inrush current or an over-excitation, enable the "Stabilization Rush" function in the configu-ration mode by configuring as ON and set an operate margin inthe next screen. The operate margin must be set for rush detec-tion. This limit must be set so that it is not exceeded in normaloperation. But it must be exceeded if an inrush current occurs.The proportion of 2nd harmonics in normal operation and in thestarting current depends in part on the type of transformer con-struction and the starting torque. As such, no general operatingmargin can be given here. The documentation contains notesstating that the proportion of 2nd order harmonics, when there isinrush current, is always over 50 % and always under 30 % whenthere is a short-circuit. Only Step 1 of the differential current trip-ping can be stabilized; Step 2 causes constant tripping. Whenelectrical restraint is activated, you should ensure that the timelag for monitoring the differential current 1 is at least 0.08 sec-onds.

Self-Monitoring

The unit is equipped with an operational readiness message forself-monitoring. It is available externally via a contact assembly.The ready for operation signal is disabled if the unit's supply volt-age drops below approximately 19 Vdc or if there is an internalmalfunction.

ConfigurationThe operating parameters may be entered in through the buttonson the front panel. To change these parameters, the control mustbe in the configuration mode. The control unit will continue tooperate while in the configuration mode. This may result in thecontrol unit accidentally issuing a breaker open command if theparameters are changed while in the operation mode.

Section 6: ConfigurationIntroductionWhen in configuration mode (simultaneous pressing of "Digit "and "Cursor "), the configuration screen can be advanced bypressing the "Select" button. A scroll function to rapidly advancethrough the parameters or increasing values can be enabled bypressing and holding the desired button. If the desired parameterwas missed while advancing through the screens, the user mayback up through a maximum of the last four screens by pressingthe "Select" and "Cursor " buttons. Should there be no entry,parameter change or other action for 60 seconds, the unit willautomatically revert into Display mode.During the configuration mode, the monitoring function is stillenabled. This means inevitably, that while adjusting parametersduring operation, it is possible to cause a relay to trip.

Configuring the RelayNote: Operating current (N.O.): The relay is enabled (i.e. in the operatingstate) when current flows through the coil. If a loss of the supply voltageoccurs, a change of state will not occur in the relay and no triggering offault conditions occur. In this mode of operation, the condition of the sys-tem should be monitored through other means than the state of the relay.Note: Idle current (N.C.): The relay is disabled (i.e. in idle state) when cur-rent flows through the coil. The relay is energized in idle state. If a loss ofthe supply voltage occurs, a change of state will occur in the relay and atriggering of fault conditions will occur.

Change Relay Function? YES/NOYES ....... The subsequent screens for the selection between oper-

ating current and idle current contact are displayed.NO ......... The subsequent screens are not displayed.

Relays 1, 2, 3, and 4 Functions A/RA choice is made between different control principles with theselection of either operating current contact (N.O.) or idle currentcontact (N.C.). An operating current output can be used if anopen circuit cannot lead to more serious faults; idle current outputperforms advanced tasks, e.g. for lines relevant to safety. Relay 3(readiness for operation) can only be operated as an idle currentcontact.A .........Operating current output (N.O.): the digital alarm output

functions as an operating current output.R .........Idle current output (N.C.): the digital alarm output func-

tions as idle current output.Note: The alarm outputs for differential protection are changeover con-tacts.

Self-acknowledging Relay ON/OFF(Description for Operating Current Output)ON ........ The relay is automatically enabled (after the configured

delay time has expired), once the fault condition is nolonger detected. Depending on how the parameter " Self-acknowledging messages " is configured, will dictatehow the control displays the error messages.

OFF ....... The relays remain disabled and the messages are shownin the display until they have been acknowledged manu-ally. The subsequent screens of this parameter will notbe displayed.

Note: Subsequent setting is blocked: " Self-acknowledging relay " " OFF " " Self-acknowledgement of messages " " ON "

Resetting Time of Differential Current 0.10 to 99.98 sOnly visible if the "Self-acknowledging relay" screen is configuredto ON.

Self-acknowledging Messages ON/OFFON ........Once the fault condition is no longer detected and the

message resetting time has expired, the message iscleared from the display.

OFF .......The messages are shown in the display until they havebeen manually acknowledged. The subsequent screen is

not displayed.Note: Subsequent setting is blocked:

" Self-acknowledging relay " " OFF " " Self-acknowledgement of messages " " ON "

Acknowledge Messages Delay Time 1 to 99 sThe fault messages are acknowledged after the configured delaytime expires. This timer is initiated when the measured valuesreturn to the configured limit + hysteresis.

Note: The following screens are used to assign the warning messages to

relays 1 to 4. The number of the relay to be enabled when the respectiveset point is exceeded has to be configured. If left as all 0s, no messagewill be issued. It does not matter what order the relay numbers areentered. As an example, if 2310 or 3102 is configured, relays 1, 2, and 3will react when this set point is exceeded.

Relay 3 is always connected to the "Ready for operation" message.

Section 7: Commissioning

PrerequisiteConnect the unit according to the wiring diagram on page 5.

Pre-adjustmentsIn order to put the unit into operation, you must:

1. Connect the auxiliary 24 Vdc power supply (Terminals 13/14);

2. Activate the Configuration mode (Press "Digit " and"Cursor ");

3. Set all parameters according to the Configuration section; and

4. Activate the Display mode (Press "Digit " and "Cursor ").

Testing with Secondary ValuesThe threshold value can be tested using three-phase test equip-ment. Single-phase test systems can generate measured valueswhich do not match the current supplied as a result of eliminatingthe phase-matching system. The control unit will behave in a sim-ilar manner to applications where matching transformers are used.

Differential Current Testing Using Single-sided Three-phase SupplyThe operating limit can be approached by slowly increasing thetest current. The tests can be carried out consecutively on thehigh- and low-voltage sides.

Threshold Value: The threshold value in A is generated from thefollowing ratio:

Id(ESDR) Differential current setting value [%]

Iw(prim) Primary transformer rated current [A]

Iw (sec) Secondary transformer rated current [A]

Id(a) Differential current threshold value

IN Rated current of the protection object (reference value)

kB Reference factor

Reference Factor k B:The reference factor is used for standardiza-tion on the reference side.

Low-voltage side:

Commissioning Using Primary ValuesPrior to commissioning a unit, the following must be verified. All test equipment must be removed from the system. here are no open circuits on any current transformer.

During commissioning, the system should be configured to permitfor the finest current adjustment. This can be accomplished by: Utilizing suitable jumpers (observe current carrying capacity) for

unit connections on the high-voltage side of the transformer;and

Disabling the automatic voltage regulator and manually adjust-ing the excitation current.

Testing for Correct ConnectionThe excitation should be set so that the generator is loaded toapproximately 20% rated current. If the connections are correct,the displayed differential current should be approximately zero.The displayed restraint current should be checked using an exter-nal measuring device. Record all measured values.

Restraint Current:

Im(sec) Measured value

Is(a) Restraint current display value on ESDR4T




kB Reference factor

The value calculated using this ratio must be the same for boththe high- and low-voltage sides. If the currents displayed are not

of approximately the same magnitude, or if high differential cur-rents are already displayed, the equipment should be shut downand the transformer assignment checked.

Testing with Cyclical SwappingWith the system off, the secondary connections of the CTsshould be rotated between phases. Turn the system on andincrease the excitation to gradually increase the load current.The resulting displayed values must be in accordance with the fol-lowing:

I Is(a) Restraint current display value

Id(a) Differential current indicated value




kB Reference factor

Im(sec) Measured value

During this test, it is possible that the threshold value may beexceeded causing the relay to trip.

If these current relationships are correct, the equipment can beshut down and the original condition restored.

Renewed Test with the Correct Connection(Measurement of the Maximum Differential Currents)Restart the unit after restoring the original connections. Test thedifferential current and the restraint current at 20 % of the ratedcurrent and compare these with the values measured from "Test-ing for Correct Connection". If the measurements match, you canslowly increase the current up to the rated current. The differen-tial currents should be approximately zero until they reach therated current. If this is not the case (e. g. with tapped transform-ers), the threshold value of the differential protection may have tobe corrected to less sensitive values.Determining the maximum differential currents during fault-freeoperation should give a starting point for working out the trippingcharacteristic (kick point). Start the short-circuited generator in de-energized condition. Select the display of the differential currents by pressing the

"Display" button (green "Differential Current I d" LED must lightup).

Next, gradually increase the generator from a de-energized con-dition to 1.2 times the rated current and record the restraintcurrents and related differential currents.

Set the threshold values of the tripping characteristic.
