Generator Overcurrent Protection
- Thread starter Power2all
- Start date
It means what it says they use a instantaneous over current element at 115% FLA, to torque control a second element that trips in 7 seconds at 226% of FLA and is set to pickup at 75-100% of FLA,
I have never seen that approach used in the US for generator protecton. Typically generator protection used is 51 Voltage Control, 51 Voltage Restraint, or 21 Distance.
It's should be able to be done with a modern relay such as the GE G30 using the flex logic or the SEL 300G, or a Basler 11g. It takes two settings (50 and 51) and uses an "and" gate to output the required protection.
