Overload

 

Threshold for generator overload (in % of Nominal power)

 

 

Step: 1% of Nominal power; Range: 0 - 200%

 

 

 

 

 

Overload Wrn

 

Threshold for generator overload warning (in % of Nominal power)

 

 

Step: 1% of Nominal power; Range: 0 - 200%

 

 

 

 

 

Overload del

 

Delay for generator overload alarm. Step: 0.1s; Range: 0 - 60.0 s

Ishort

 

Shutdown occurs when short circuit limit Ishort limit is reached.

 

 

Step: 1 % of Nominal current; Range: 100 - 500 %

 

 

 

 

 

2Inom del

 

IDMT curve shape selection. 2Inom del is Reaction time of IDMT

 

 

protection for 200% overcurrent Igen = 2* Nominal current.

 

 

Step: 0,1 s; Range: 0,1 - 20 s

 

 

IDMT is “very inverse” generator over current protection. Reaction time is

 

 

not constant but depends on generator over current level according

 

 

following formula. Reaction time is limited up to 900 sec = 15 minutes.

 

 

IDMT protection is not active for Reaction time values longer than 15

 

 

minutes.

 

 

2lnomdel * Nomincurrent

 

 

ReactionTime +

 

 

 

lgen * Nomincurrent

Curr unbal

 

Threshold for generator current asymmetry (unbalance).

 

 

Step: 1% of Nominal current; Range: 1 - 100% of Nominal current

 

 

 

Curr unbal del

 

Delay for generator current assymetry. Step: 0.1 s; Range: 0 - 60.0 s

Gen >V

 

Shutdown level for generator overvoltage. All three phases are checked.

 

 

Maximum out of three is used.

 

 

Step: 1% of Nominal voltage; Range: Gen >V Wrn -200%

 

 

 

Gen >V Wrn

 

Warning level for generator overvoltage. All three phases are checked.

 

 

Maximum out of three is used.

 

 

Step: 1% of Nominal voltage; Range: Gen <V Wrn - Gen >V

 

 

 

Gen <V Wrn

 

Warning level for generator under voltage. All three phases are checked.

 

 

Minimum out of three is used.

 

 

Step: 1% of Nominal voltage; Range: Gen <V - Gen >V Wrn

 

 

 

Gen <V

 

Shutdown level for generator under voltage. All three phases are checked.

 

 

Minimum out of three is used.

 

 

Step: 1% of Nominal voltage; Range: 0% - Gen <V Wrn

Step: 1% of Nominal voltage; Range: 0 - 100% of Nominal voltage

 

 

 

Volt unbal del

 

Delay for generator voltage unbalance alarm.

 

 

Step: 0.1s; Range: 0 - 60.0 s

 

 

 

Gen >f

 

Shutdown level for generator over frequency.

 

 

Step: 0.1% of Nominal frequency; Range: Gen > Wrn - 200.0%

 

 

 

Gen >f Wrn

 

Warning level for generator over frequency.

 

 

Step: 0.1% of Nominal frequency; Range: Gen <f Wrn - Gen >V

 

 

 

Gen <f

 

Shutdown level for generator under frequency.

 

 

Step: 0.1% of Nominal frequency; Range: 0.0 - Gen <f Wrn

 

 

 

Gen <f Wrn

 

Warning level for generator under frequency.

 

 

Step: 0.1% of Nominal frequency; Range: Gen <f - Gen >f Wrn
