rion, the feedback information of the assigned breaker must inform the device about
the breaker position.
The time overcurrent protection for earth current allows the breaker criterion only if an
unequivocal relationship exists between its assigned side or measuring location and
the feedback information of the breaker (SwitchgCBaux S1, SwitchgCBaux S2 to
SwitchgCBaux M5, addresses 831 to 840).
Timers There are no specific procedures on how to set the delay times CB Open Timeat ad-
dresses1711), Active Time (address 1712) and Stop Time (address 1713).
These time delays must be based on the specific loading characteristics of the equip-
ment being protected, and should be set to allow short-term overloads associated with
dynamic cold load conditions.
Cold Load Pickup
Values
The dynamic pickup values and time delays associated with the time overcurrent
stages are set in the related addresses of the stages themselves.
