Hermetically sealed voltage & current transformers - CT VT
(OP)
Good day,
In our network we have several Hermetically sealed voltage and current transformers ranging from 33 - 220kV.
There are several which have developed oil leaks.
Can these be repaired as they are Hermetically sealed units?
We would preferably repair them in-house / on site as we are a remote Sub Africa utility.
Thank you

If it uses a metallic bellows expansion system, I would recommend discussing it with the manufacturer.
Often times it's not as easy as it looks to repair a leaking instrument transformer.
