Grounding Low Voltage Generators
Grounding Low Voltage Generators
(OP)
I am interested to know how would one achieve grounding of a 400 volt, 1600 kilowatts generator. That is to say with the genset capable of 2300Amp how would grounding be achieve given the amount and size of cable that would have to be used between the nuetral terminal of the generator and the grounding rod. How would all this cable be connected to a rod.






RE: Grounding Low Voltage Generators
You will need to include an earth fault relay on the connection to earth, or possibly in the residual connection of the 3 lines and neutral. If you're using an earth rod then the E/F setting will be fairly low - a few tens of amps - so you will probably need a dedicated CT.
