in recloser, breaker failure and synchronism functions. The settings are
Number of Switchgear, Maximum KI2t, KI2t Integ. Time, Maximum
Openings, Max.Openings 1 hour and Snapshot Events.
These settings correspond to the initialization of (KI)
counting of number of openings and closings of the switchgear
configured as breaker. These Counters allow the breaker Maintenance.
They are used to cumulate the breaker ageing produced by a trip or a
breaker opening. In order to incorporate the breaker historic, in case of
existing breakers, the system allows assigning an initial value to
accumulated amperes, and to the number of opening and closing
operations.
