Connection DiagramsP92x/EN CO/F22MiCOM P921/P922/P923 Page 3/101. ANALOGUE INPUTSThe MiCOM P921-P922 and P923 relays have 4 voltage inputs: one voltage inputfor the residual voltage and 3 phase voltage inputs.1.1 VT inputsThe following figures present different configurations of VTs.1.1.1 3VTs (phase-neutral) configurationSelect the « 3V PN» configuration in the « CONFIGURATION » menu and in the« GENERAL » sub-menu.The 3 phase voltages VA, VB, VC are then measured by the MiCOM relay.3VTs CONFIGURATION (Phase-Neutral)ACPhase rotationBPower supply+-3334WDRL1373536642WatchdogOutput contacts programmableRL1MiCOM P92*RL212108RL241RL31614RL34243RL42018RL44445RL531RL5464950See note 1RL6RL775911RL6RL7Programmable inputs :EL1+22_2426RL81315LEDsRL84 programmable LEDsEL2EL3EL4EL5+ _2817+ _1921+ _2325+ _27See note 2*29303132+_-EarthconnectionCommunication port RS485(* System end resistance.For last relay, connect 30 and 32 together).Notes :(1) Additional hardware for MiCOM P922 and P923 relay(2) Additional hardware for MiCOM P922 and P923 relayScheme representing MiCOM relay offP0389ENaFIGURE 1: 3VTs CONNECTION
