Gener protect
The content depends on programmable protections settings. This list contains pre-set protections from
default ar fixed protections, which are always present:
OverldStrtEval
[ % ] (FV)
Specifies the overload level, where the protection evaluation starts (see figure at
2PovrldStEvDel
). Under
this level the protection is not active.
Step:
1 % of
Nomin power
Range:
100 – 200 %
Force value possibility: Yes
2POvrldStEvDel [ s ]
IDMT curve shape selection.
2PovrldStEvDel
is the Reaction time of IDMT protection for 200% overload
Pgen = 2*
OverldStrtEval
.
Step:

s
Range:
0,0 - 600,0
s
Protection:
BreakerOpen & Cool-down.
IDMT is inverse proportional to the generator overload. The higher the overload gets the less time will elapse
before the protection activates.
When the IDMT protection is activated the GCB is opened, the event is recorded in the Alarmlist and History,
and the engine will cool down and stop.
Where Reaction time is the amount of time from IDMT detection to the opening of the GCB.
Hint:
The maximum allowable Reaction time is 3600 sec.
Reaction time is the amount of time from IDMT detection to the opening of the GCB.
