High Voltage Transformers

What is a high voltage transformer?

Transformers are normally used in high voltage laboratory for testing purpose. This transformer is subjected to transient voltages and surges. To withstand these impulse voltages, the insulation of transformer is carefully designed. This type of transformer is generally oil immersed. The high voltage transformers used for HT cable testing purpose are to supply also sufficient electric current and that is why the cooling system of these transformers is very carefully designed. 

Up to voltage 500 KV, generally single unit of high voltage transformer is used. But for higher voltage rating more than one transformer, are connected in cascade to produce required high voltage
