Co Gen Trips on Neutral Current
Co Gen Trips on Neutral Current
(OP)
Hello,
A job I did last year suddenly started having problems. It is a 600KW Co Generation unit at a hospital. The operating voltage is 480V. Everything worked fine for months and now it seems to be tripping on a "Neutral Current Fault". I don't have any more detail as I haven't been back to the site but everyone involved is stumped. Any idea what could cause this and what the resolution might be?

Bad connection in the neutral sensing?

I don't believe there is any new equipment i the hospital and I have not been to the site to check any connections.

The previous trauma may quite well have done damage that left the machine susceptable to further damage by thermal cycling.
I saw a coupling blown off of a 350 KW 1200 RPM by an out of sync. closure.

Is this generator feeding the critical branch of the hospital? I wouldn't want to be under the knife in a O.R.
with a generator tripping out.
