Great Video! Is there an oil tap down at the bottom where you can hook up a glass syringe and extract a sample for regular maintenance over the recloser life?
The OCR tank does not have a way to drain oil. Depending on contact type, regular scheduled OCR maintenance is a changeout and rework every 3-5 years. This was left until the OCR failed at 16 years. I do wish the run-to-fail philosophy was not so popular.
Of course something like that is possible. If the transformer is a single bushing primary, the ground lug is the neutral return for the high side coil. Contact your local utility for an inspection.

I am having surges , I think I saw a tiny bit of like fire where the ground connection to transformer is, is that possible.

Do you referb the old ones to be put back into service
Yes, a failed recloser will be rebuilt if possible. These are run to fail, so 10-20 years on the line.
