Outdoor Oil Immersed Potential (Voltage) Transformer

outdoor oil filled potential transformer

Outdoor Oil Immersed Potential (Voltage) Transformer is a type of instrument transformer whose function is to step down voltage in an electrical system to a level measurable by various metering instruments.

We manufacture Outdoor Oil Filled Potential (Voltage) Transformer without top expansion tank upto 33kv system voltage. This design has a single tank. The core and windings are contained in the lower tank. The primary winding is taken through the HT insulator to be connected to the primary terminal arranged at the top of the HT insulator. The secondary windings are connected to secondary terminals placed on the lower tank.

The Outdoor Oil Filled Potential Transformer without Top Conservator Tank is generally used for medium system voltages like 11, 33 KV etc. In such lower system voltages, uniform insulation is sufficient to withstand high voltages and is feasible from both Technical & Economical point of view.
