Limit for the generator overload alarm in % of the nominal power. The delay
of this alarm is adjustable by the setpoint Overload Del.
Delay for the generator overload alarm. The limit for this alarm is adjustable
by the setpoint Overload BOC.
IDMT curve shape selection. Amps IDMT Del is Reaction time of IDMT
protection for 200% overcurrent
IDMT is “very inverse” generator over current protection. Reaction time is not
constant but depends on generator over current level according to the
following formula:
HINT:
Reaction time is limited to 3600 = 60 minutes. IDMT protection is not active
for Reaction time values longer than 60 minutes.
I
gen
is maximal value of all measured phases of generator current.
