6.9.3 Setting guidelinesThe parameters for the Pole discordance protection CCRPLD (52PD) are set via the localHMI or PCM600.The following settings can be done for the pole discrepancy protection.GlobalBaseSel: Selects the global base value group used by the function to define (IBase),(VBase) and (SBase).Operation: Disabled or EnabledtTrip: Time delay of the operation.ContactSel: Operation of the contact based pole discrepancy protection. Can be set:Disabled/PD signal from CB. If PD signal from CB is chosen the logic to detect polediscrepancy is made in the vicinity to the breaker auxiliary contacts and only one signal isconnected to the pole discrepancy function.CurrentSel: Operation of the current based pole discrepancy protection. Can be set:Disabled/CB oper monitor/Continuous monitor. In the alternative CB oper monitor thefunction is activated only directly in connection to breaker open or close command(during 200 ms). In the alternative Continuous monitor function is continuously activated.CurrUnsymPU: Unsymmetrical magnitude of lowest phase current compared to thehighest, set in % of the highest phase current.CurrRelPU: Current magnitude for release of the function in % of IBase.6.10 Broken conductor check BRCPTOC (46)6.10.1 IdentificationFunction description IEC 61850identificationIEC 60617identificationANSI/IEEE C37.2device numberBroken conductor check BRCPTOC - 466.10.2 ApplicationConventional protection functions can not detect the broken conductor condition.
