maintenance is mandatory now.
The protective relay will make a alarm decision based on the curve that the user provides.
The relay will monitor the frequency of ON/OFF cycles. The User can set thresholds for the maximum allowed sum
of interrupt currents and the maximum allowed sum of interrupt currents per hour. By means of this alarm,
excessive switchgear operations can be detected at an early stage.
