Greetings,
For Hydro Generators, is it common to combine both a resistor and capacitor/surge arrestor for protection of the stator? I've seen generators with neutral grounded via a resistor.
How common is it to have a surge grounded neutral on the machine, which would consist of both the resistor, capacitor and a SA?
Also, for capacitor sizing, are the line-to-line Voltage a primary design parameter?
For surge arrestor, my understand it would be the nominal voltage of the system and whether the generator is effectively grounded.
Best Regards,
EE
