SIRLevel: The setting of the parameter SIRLevel is by default set to 10. This is asuitable setting for applications with CVT to avoid transient overreach due to the CVTdynamics. If magnetic voltage transformers are used, set SIRLevel to 15 the highest level.IMinOp: The minimum operate current for the SIR measurement is by default set to20% of IBase.3.6.7.3 Setting parametersTable 68:ZSMGAPC Group settings (basic)Name Values (Range) Unit Step Default DescriptionIBase 1 - 99999 A 1 3000 Base value for current measurementVBase 0.05 - 2000.00 kV 0.05 400.00 Base value for voltage measurementPilotMode DisabledEnabled- - Disabled Pilot mode Disable / EnableZreach 0.1 - 3000.0 ohm 0.1 38.0 Line impedanceIMinOp 10 - 30 %IB 1 20 Minimum operating current for SIRmeasurementTable 69:ZSMGAPC Group settings (advanced)Name Values (Range) Unit Step Default DescriptionDeltaI 0 - 200 %IB 1 10 Current change level in %IB for fault inceptiondetectionDelta3I0 0 - 200 %IB 1 10 Zero seq current change level in % of IBDeltaV 0 - 100 %VB 1 5 Voltage change level in %VB for faultinception detectionDelta3V0 0 - 100 %VB 1 5 Zero seq voltage change level in % of VBSIRLevel 5 - 15 - 1 10 Settable level for source impedance ratio3.6.8 Faulty phase identification with load encroachmentFMPSPDIS (21)Function description IEC 61850identificationIEC 60617identificationANSI/IEEE C37.2device numberFaulty phase identification with loadencroachment for mhoFMPSPDISS00346 V1 EN211MRK504116-UUS C Section 3IED application311Application manual
