Gener Protect
NOTE:
All electric protections when activated result in Trip.
The generator protections are evaluated from different voltages based on ConnectionType setting:
 3W 4Ph – Ph-Ph voltage
 3W 3Ph – Ph-Ph voltage
 Split Ph – Ph-N voltage
 Mono Ph – Ph-N voltage
GenerProtect [ENABLE/DISABLE]
ENABLE: Generator protections of the controller are active.
DISABLE: Generator protections of the controller are inactive.
Overload Trp [%]
Threshold for generator overload (in % of Nominal power)
Step: 1% of Nominal power
Range: 0 – 200%
Overload Del [s]
Delay for generator overload alarm.
Step: 0.1 s
Range: 0 – 600.0 s
Short Crct Trp [%]
Trip occurs when generator current reaches Short Crct Trp limit.
Step: 1 % of Nominal current
Range: 100 – 500 %
Short Crct Del [s]
Delay for generator shortcurrent alarm.
Step: 0.01 s
Range: 0.00 – 10.00 s
Amps IDMT Del [s]
IDMT curve shape selection. Amps IDMT Del is Reaction time of IDMT protection for 200%
overcurrent Igen = 2* Nomin Current.
Step: 0.1 s
Range: 0.1 – 60.0 s
IDMT is “very inverse” generator over current protection. Reaction time is not constant but depends on
generator over current level according following formula.
Igen is maximal value of all measured phases of generator current.
NOTE:
Reaction time is limited up to 3600 sec = 60 minutes. IDMT protection is not active for Reaction time
values longer than 60 minutes. Logical binary output GenStartStop must be configured to evaluate
IDMT protection.
Amps IDMT Del * Nomin Current
Reaction time =
Igen - Nomin Current
