Description
The overcurrent alarm is based on IDMT principle. The reaction time of an IDMT
alarm is not fixed, but depends on how much is the protected value above the limit
). The higher is the overcurrent, the shorter the reaction
time will be. All mains phases are evaluated.
The behavior of the overcurrent alarm is adjusted by the following setpoints:
defines the reaction time of the protection
when the current is twice the amount of nominal value.
set the nominal current level, where the alarm
starts to be evaluated. The reaction time is infinite at this point.
