GF relaying on parallel off grid generation
GF relaying on parallel off grid generation
(OP)
Have multiple generators on off grid system. All generators are 2400/1385 wye with hard ground and ground fault relaying.
When running two or more units in parallel (there are 6 units total, dispersed over several miles) do I need to transfer trip any ground fault relay action from a running unit to the the other running units?
Each unit is earthed individually. The connecting distribution system is 2400v three phase, three wire.
Three of the generating units are 480 volt delta with a close coupled 480/2400 wye auto transformer with center grounded.
The other three generators are wound 2400/1380 wye and similarily grounded.

If it is broken, fix it. If it isn't broken, I'll soon fix that.
