Effect of improper storage of oil-filled potential transformer
Effect of improper storage of oil-filled potential transformer
(OP)
We have a 80,500:115 V oil-filled potential transformer stored horizontally instead in vertical position for almost 13 years already.
What are the possible effects/problems may encounter on the performance of the PT when not properly stored? Does it affects the insulation or accuracy of the PT?
Hope you can share your experiences on this situation.
regards,
GRAEE

I'd give it a PD/DDF test prior to service, and analyse an oil sample to determine if you have moisture ingress.
