Generator Neutral Arrester
Generator Neutral Arrester
(OP)
Hi,
I have seen the standard generator single line diagram of Siemens always shows the surge arrester between generator neutral grounding transformer and ground for gas turbine generator started with static frequency converter.
The question is that why the arrester is need to be connected bewteen NGT and ground ?
I have not seen other generator manufacturers connect such arrester like this.
Can anyone explian why it is need for machine started with SFC ?
Thank you very much.

In this condition, the surge arrester protects against overvoltages
