Hi Karthick,

1. Regarding IDMT curves, considering Is the set threshold:
-The minimum trip level is 1.025 Is

- The level at which the tripping time becomes independent is 40 Is.
This is valid as long as measured currents are within the dynamic range of the CT inputs.

2. Regarding thermal overload and negative sequence overcurrent threshold, the Full load amps (FLA) parameter can be defined between 0.1 and 3.25 pu.

Thanks Gregory.

I will share these answers with ETAP Technical team through Help Centre to prepare the Power Logic P7 Relay.
