Can anyone help with the solution on 200kva diesel generator that is earthed that has shut down during thunderstruck refuse to run. keep given "low pressure alarm" and "low voltage alarm" even though the fuse on the AVR is blown by the thunderstruck and changed.

 

Apyzo... do you mean lightning struck an OHV (overhead) transmission line connected to a lower voltage generator via step-down transformer?

Hi Phil-

The thunder struck and the generator stop running, and I detected that the fuse on the AVR is blown so I changed the fuse but when start it keep given low oil pressure and voltage alarm mean while. I have the oil filters.
