Facilities are required).interfacing substation control or SCADA relay ? Good feature/price ratioAREVA FlushAPPLICATIONThe MiCOM P111 provides a wide range of protectionfunctions.Typical applications are:Underground MV cablesInsulated or resistance earthed neutral systemsMV subscribers, Industry, TransportAdvanced LV application

(specifically where com-munication facilities are required)To have good ratio:price to functionality used in theapplication, there are different models of P111available.Differences between models are shown in the TablebelowGLOBAL FUNCTIONSThe following functions are generally available in alldevices (see table below) :Operate in 1, 2, or 3-phase arrangement Two setting groups, selected from the relay menu, binary input or system35 mm DIN rail or flush mounted case (option)True RMS phase current value measurement within a frequency range from 10Hz to 1000HzEarthfault current value measurement within a frequency range from 40Hz to 70Hz4 digit LED display5 button keypad to input settings and configure the relayFault record for the 3 most recent tripsFUNCTIONS OVERVIEW ModelsABCEF50/51Three-phase overcurrent I (DT)????50/51Three-phase overcurrent I (DT or IDMT)?????50/51Three-phase overcurrent Ip (DT or IDMT)?????50N/51NEarth fault (single phase) overcurrent ????Io

.All stages have reset timer to reduce clearance timesintermittent faults occur.All stages can be separately configured to make a tripor alarm.The MiCOM P111 relays have separate instantaneousand delayed information for all stagesThe range of settings can be selected by orderingcode.Three Phase Overcurrent Protection (50/51) The independent stages are available for phase faultprotection.For the first (Ip) and second stage (I) theuser may independently select definite time delay orinverse time delay with different type of curves (SI, VIor EI).The third stage can be configured with definitetime only.Each stage and related time delay can be programmedto provide maximum selectivity.All stages have reset timer to reduce clearance timesintermittent faults occur.All stages can be separately configured to make a tripor alarm.The MiCOM P111 relays have separate instantaneousand delayed information for all stagesThe range of settings can be selected by for PTCSensors (38)If T1-T2 input is configured as PTC input andresistance of the sensors' loop connected to input :T1-T2 increase, then protection operates instantaneously.Up to 6 PTC sensors can be connected in series.The PTC input operates instantaneously.This function can be configured to make a trip or alarm.External Protection TripThe external protection trip operates if an input state,which is programmed to this function (ZZ), changes itsstate.The protection can be configured to "trip" or send a"warning signal" (alarm).Trip operation is instantaneousA2 A1 13 14 23 24 T1 T2 S1 S2 L3 L1 L2 Vx 33 34 44 42 41 V2 V1 Tr+ Tr- Tr+ Tr- RS 485 RS 485 I / O cardIo Io RS 485 I / O cardIo P1 P2 P3 P4 A2 A1 13 14 23 24 T1 T2 S1 S2 Vx 33 34 44 42 41 V2 V1 P1 P2 P3 P4 1 IL1 IL2 IL3 35 mm DIN rail caseFlush mounted caseBinary contactor PTC RS 485 Io Binary contactor PTC Output Relay Latching (86)RL2 and RL3 relays can be latched.Reset of the latched outputs is possible by logic inputs,front panel operator interface or by remotecommunication

CB or Contactor ControlMiCOM P111 allows controlling of circuit breaker orcontactor.The user may select switch type byprogramming main output relays.The selectionIt is possible to make local (via selected binary input) orremote
