9.11.4 Event function EVENT M11751-2 v5Prepare the IED for verification of settings as outlined in section "Preparing fortest" in this chapter.During testing, the IED can be set when in test mode from PST. The functionalityof the event reporting during test mode is set in the Parameter Setting tool inPCM600.• Use event masks• Report no events• Report all eventsIn test mode, individual event blocks can be blocked from PCM600.9.11.5 Fault locator LMBRFLO M14955-2 v7Prepare the IED for verification of settings outlined in Section "Preparing the IEDto verify settings".The Fault locator function LMBRFLO depends on other functions to workproperly, that is, phase selection information from distance protection function andanalog information supplied by the trip value recorder function. Check that properbinary start and phase selection signals are connected and voltage and currentsignals are configured (parameter settings).The result is displayed on the local HMI or via PCM600. Distances to faults for thelast 100 recorded disturbances can be found on the local HMI under Main menu/Disturbance Records/Disturbance #n(n = 1–100)/General InformationIf PCM600 is used, the result is displayed on the recording list after upload,including loop selection information.Table 19:Test settingsParameter ConditionI Higher than 30% IrHealthy conditions U = 63,5 V, I = 0 A & ZF = 0°Impedance |Z| Test pointNote:• Zx£ (X0 + 2 · X1)/3 For single-phase faults• Zx£ X1 For three and two phase faults• Zx£ (X0 + 2 · X1 XM)/3 For single-phase fault with mutualzero-sequence currentImpedance angle ZF Test angle• ZF arctan[(X0 + 2 · X1) / (R0 + 2R1)] For single-phasefaults• ZF arctan(X1/R1) For two-phase faultsSection 9 1MRK 506 383-UEN ATesting functionality by secondary injection166 Line distance protection REL650 2.2 IECCommissioning manual
