HV bushing

There is a HV bushing(220 KV) giving a red indication of its oil level.
There is possibility to check the indication if it is right or not by opening the top filling cap without any problem for the oil insulation, and if the level is low it is possible to add oil of the same type used for the transformer. Thanks.

Without the assistance of someone who had done the procedure before or specific guidance from the manufacturer, I would be very careful.

Possible concerns include moisture intrusion, particle contamination, incorrect level/pressure relationship, improper reassembly of seals etc.

What is really dangerous in any refilling is the entrance of moisture, most gaskets are dry and aged so care of replacing them with the adecuate ones.
If not your problem would be big.

You must as it is above consult an expert like bushing factory, so as to have the procedure.

Also beware of the quantity of oil that in little volume depends its level with the temperatura.
