Generator controller settings?

Hello Everyone.

Attached is some settings for Caterpillar EMCP controller. How do I use these settings in the power system software like Etap?

It looks like you have an inverse curve combined with a definite time one. Inverse has a factory default pickup of 105% with a time multiplier of 0.27. Def Time has pickup of 110% with a 10s time delay. I do not know ETAP that well but I am sure it has relay trip current curves you could call up from an ETAP model for your relay. These then get displayed as a TCC curve, displayed on the SLD, etc.

The inverse curve is an IEC Standard Inverse type judging from the constants. Pretty much any of the European numerical overcurrent relays will have both IDMT and DT settings which use the IEC curve.
