Gener Protect
NOTE:
All electric protections when activated result in shutdown.
GenerProtect [ENABLE/DISABLE]
ENABLE: Generator protections of the controller are active.
DISABLE: Generator protections of the controller are inactive.
Short Crct Trp [%]
Shutdown occurs when generator current reaches Short Crct Sd limit.
Step: 1 % of Nominal current
Range: 100 - 500 %
Short Crct Del [s]
Delay for generator shorcurrent alarm.
Step: 0.01s
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.
Amps IDMT Del * Nomin Current
Reaction time =
Igen - Nomin Current
Igen is maximal value of all measured phases of generator current.
NOTE:
Reaction time is limited up to 900 sec = 15 minutes. IDMT protection is not active for Reaction time
values longer than 15 minutes.
EXAMPLE of Reaction time for different over current levels. Values in column 200% are IDMT Curr
Del.
