ups fault
(OP)
im having problems with 625kva ups which keeps dropping its internal by-pass.
the supply has been tested and shown to healthy,the inverter and thyrister stacks on the ups have been replaced.
the fault is very intermittent,as shows itself wether the ups is on load or not.
some ideas or thoughts would be most welcome.

the ups runs fine but as soon as you close input2 from the input splitter the ups keeps dropping the thyrister switch.
we have run the ups on a seperate transformer and on its generator which have been fine.

You probably will get some conjectures from some here, but they are just that.

This may be a bit harsh but so it is in the fiekd.
What kind of plant is it actually...Good or agressive environment..?? salty, sandy, wet, chemical, sewage...or a perfect air conditioned computer center...
