	Table 4‐17 Generator Protect Setpoints
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

		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

		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
Gen f del		Delay for generator under frequency and over frequency alarm.
		Step: 0.1s; Range: 0 - 60.0 s
