6F2T0207 (0.01)GRE200 (5,6)- 628 -5.4.1 VCT typesThere are two types (VCT4A and VCT4B) and one type is selected depending on the relayapplications.Note: VCT4A is selected for the IED hardware model GRE200-5 (which can be read froman ordering code position “7” of hardware). Conversely, VCT4B is selected for themodel GRE200-6. Refer toChapter Installation and replacement (→page 1036),and seeAppendix: Ordering (→page 1133) for that.(i) VCT4AFigure 5.4-2 shows VCT4A type, which agrees with five voltages and four currents inputs.VoltageCurrentVoltageVoltageVoltageVoltageCurrentCurrentCurrentVCT4AIL112IL234IL356Ie78VL1910VL21112VL31314Ve1516Vs1718Figure 5.4-2 Transformer module (VCT4A)(1)Note: The channel number is used to represent the terminal location when settingthe ratio of the CT or the VT. SeeVCT ratio setting (Chap. 5.4.3).(2)Note: The residual quantities can be derived by the means to the calculation whenIe signal is not given straightforward. SeeCT for zero-phase sequencecurrent (Chap. 5.4.5(ii)).(3)Note: Reference voltages can be used in Voltage check (VCHK) function; seeChapterRelay applications: Voltage check relay (→p. 280).Terminal screwnumbersInputsignalsTypes ofinputsAC analog inputchannels(1)1 2 IL1 Current Ch13 4 IL2 Current Ch25 6 IL3 Current Ch37 8 Ie(2) Current Ch49 10 VL1 Voltage Ch511 12 VL2 Voltage Ch613 14 VL3 Voltage Ch715 16 Ve(2) Voltage Ch817 18 Vs (3) Voltage Ch9
