Hi All,
I am a new member to this forum. I would appreciate if any one can advise me on the following:
Application: 3 x captive generator (1680kVA each) with step-up transformer and connected to utility grid
1) What is the industrial norm for grounding an LV AC generator neutral? solid or isolated or through a resistance?
2) what is the recommended practice for protective relays in above cases?
3) There is a suggestion to go for device 59 (over voltage) relay fed from broken-delta on generator end and also for the HV side of transformer. Is it the correct practice?
Thanks in advance,
