Transformer oil testing

[SA07]

Hi
The insurance requests to do tansformer oil testing yearly.
Should we do same for hermetically sealed transformer and transformer with DGPT?

Do you have a conservator?

These models do not have a conservator.

Hermetically sealed transformers do not require yearly testing unlike the conservator transformers. These are not designed for oil top up that easily and better to take samples only if & when required.
You can approach the manufacturer and the insurance authority for the periodicity with hermetically sealed transformers.
