However here therequired direction of P & Qmeasurement is towards busbar(Not per IED internal defaultdirection). Therefore anglecompensation have to be used inorder to get measurements inaliment with the requireddirection.Mode Selection of measured currentand voltageL1L2 Only UL1L2 phase-to-phasevoltage is availablek Low pass filter coefficient forpower measurement, U and I0.00 Typically no additional filtering isrequiredUGenZeroDb Zero point clamping in % ofUbase25 Set minimum voltage level to25%IGenZeroDb Zero point clamping in % ofIbase3 Set minimum current level to 3%UBase (set inGlobal base)Base setting for voltage level inkV35.00 Set LV side rated phase-to-phase voltageIBase (set inGlobal base)Base setting for current level inA495 Set transformer LV winding ratedcurrentSBase (set inGlobal base)Base setting for power in MVA 31.5 Set based on rated power15.2 Gas medium supervision SSIMG GUID-358AD8F8-AE06-4AEA-9969-46E5299D5B4B v315.2.1 IdentificationGUID-AD96C26E-C3E5-4B21-9ED6-12E540954AC3 v4Function description IEC 61850identificationIEC 60617identificationANSI/IEEE C37.2device numberInsulation gas monitoring function SSIMG - 6315.2.2 Application GUID-A840E38C-CC42-4995-A569-A6092DDB81B2 v5Gas medium supervision (SSIMG) is used for monitoring the circuit breakercondition. Proper arc extinction by the compressed gas in the circuit breaker is veryimportant. When the pressure becomes too low compared to the required value, thecircuit breaker operation shall be blocked to minimize the risk of internal failure.Binary information based on the gas pressure in the circuit breaker is used as an1MRK 505 393-UEN B Section 15MonitoringLine differential protection RED650 2.2 IEC 327Application manual
