Inspection/Maintenance item for Major Overhaul Steam Turbine Generator
Inspection/Maintenance item for Major Overhaul Steam Turbine Generator
(OP)
My company using an Mitsui-ABB Steam Turbine with Meiden Brushless Alternator 27500KVA, unfortunately after more than 10 years of continues operation, this generator never been major overhauled, we only do minor overhaul every two years.
We did'nt have the complete manual book, so we are definetedly confuse about what we should do on major overhaul (Electric works for Generator).
Could anybody explain to me, what is the work item (Electrical work) for the Generator's major overhaul, what should we check or inspect, what parts should we replace,and what is the time interval for major overhaul?

A PD test is totally different than a Hipot. Hiot is a pass/fail test. PD is a life expectancy prediction. It is a science best left to the professionals in the field.
Other than those items, the only other tests we did were for protective relaying to ensure our CTs were measuring properly and we would test our relays for proper operation.

If it is broken, fix it. If it isn't broken, I'll soon fix that.
