What is the process for transformer oil filling in a conservator?

The process for transformer oil filling in a conservator involves several steps. First, the conservator tank is inspected for cleanliness and integrity. Then, the transformer oil is heated to reduce viscosity, facilitating easier filling. The oil is pumped into the conservator through a filtration system to remove impurities. Finally, the filling is monitored to ensure the correct oil level is maintained, preventing air entrapment and ensuring optimal insulation performance.
