Field failure Of Generator
Field failure Of Generator
(OP)
I set the following figures for field protection(40)
Alarm angle : 15 degree
(Alarm)
Xa1 : 3 Ohm
Xb1 : 44.8 Ohm
Time Dealy : 7 s
(Trip)
Xa2 : 2 Ohm
Xb2 : 16.8Ohm
Time Delay : 0s
In these settings, I have tripping of ACB for Generator due to field failure. I triy to troubleshooting for it. Can anybody advise what I should check for it ?

RE: Field failure Of Generator
The 0 time delay on trip jumps out at me. Normally this would be a few tenths of a second or more.
If you suspect an actual loss of excitation, check the field current and output power factor.
