With this value the new calculated value isimmediately given out without any filtering (that is without any additional delay).When k is set to value bigger than 0, the filtering is enabled. A typical value for k=0.92in case of slow operating functions.8.8.5 Technical dataTable 123:GOPPDOP, GUPPDUP technical dataFunction Range or value AccuracyPower level (0.0–500.0)% ofSBase ± 1.0% of Sr at S < Sr± 1.0% of S at S > Sr(1.0-2.0)% ofSBase < ± 50% of set value(2.0-10)% ofSBase < ± 20% of set valueCharacteristic angle (-180.0–180.0) degrees 2 degreesTimers (0.010 - 6000.000) s ± 0.5% ± 25 ms8.9 Negative sequence based overcurrent functionDNSPTOC8.9.1 IdentificationFunction description IEC 61850identificationIEC 60617identificationANSI/IEEE C37.2device numberNegative sequence based overcurrentfunctionDNSPTOC3I2>IEC09000132 V2 EN461MRK 504 135-UEN A Section 8Current protection197Technical manual
