Transformer Maintenance Practise
Transformer Maintenance Practise
(OP)
Hello to everyone this is my first post so as a little background I work for a medium sized electrical utility in Ontario Canada. I have been put in charge of building a new maintenance program for our substations and am in the process of collecting information.
We are starting with power transformers and are trying to build a schedule around testing and inspection. All of our transformers are liquid filled and range in secondary voltage from 4.16 to 44kv and primary voltage from 13.2 to 250kv
I have been looking at some books and documents but so far I have been reading through the second edition of Paul Gills Electrical Power Equipment Maintenance and Testing. It is a good reference but I wanted to see what other were doing and thought this may be a good place to pose the question.
So what kind of maintenance and testing schedule are you following for Power Transformers?
And what other books or references should I look into?

Many of my industrial clients tested on a three-year cycle.

However, I would think manufacturer's recommendations would be a good place to start and many NETA guidance would still apply.

Time based maintenance is rather an expensive thing in present day world.

The following American standards are great- ANSI/IEEE C57.93 Transformer Installation &maintenance(oil filled) C57.94 (dry type) IEEE 62- Diagnostic field testing and PC57.143-2008 Draft Std on Trf monitoring.
RE: Transformer Maintenance Practise
comprehensive list of references that any transformer maintenance engineer would find great use. Specifically, the SD Meyer's guide I found very useful.
Star to you.

You could do worse than read the J&P Transformer Book. Pricey but worth it if you do a lot of work with transformers.

You are correct. And now I have looked in my library I was thinking of the new switchgear manual anyway!

As scotty said, switch gear manual can be down loaded free.
