Top Tank Outdoor Oil Immersed Potential (Voltage) Transformer

Top Tank Outdoor Oil Immersed Potential Transformer

Top Tank Outdoor Oil Immersed Potential (Voltage) Transformer is a voltage transformer design in which there are two tanks. This is a special kind of voltage transformer and is used generally for higher system voltages like 66, 132 KV etc. Top tank outdoor oil immersed potential transformer is also known as top tank outdoor oil filled potential transformer or voltage transformer

The lower tank consist of primary windings, secondary windings & core. The upper tank is used due to the Bushing limitations to withhold Graded Insulation of HV Windings. Other purpose to provide a conservator tank is for oil expansion during high temperatures.

Macroplast manufactures top tank outdoor oil filled potential (Voltage) transformer upto 132kv system voltage. The top tank acts as an expansion chamber for the transformer. This kind of design has two tanks. 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 on the top tank. The secondary windings are connected to secondary terminals placed on the lower tank. In this design, the top tank provides space for expansion of oil
