Setting guidelines

The parameters for the Pole discordance protection CCRPLD (52PD) are set via the local
HMI 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 Enabled
tTrip: 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 pole
discrepancy is made in the vicinity to the breaker auxiliary contacts and only one signal is
connected 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 the
function 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 the
highest, set in % of the highest phase current.
CurrRelPU: Current magnitude for release of the function in % of IBase.
