What is a High Voltage Transformer?
A high voltage transformer is a type of transformer that operates at a high voltage level. High voltage transformers are normally used in high voltage labs for testing purposes. These high voltage transformers are subjected to transient voltages and surges during their normal operation when the insulation under test breaks down.
To withstand these impulse voltages, the insulation of these transformers must be carefully designed. These are usually single-phase core-type transformers.
This type of transformer is generally oil immersed. Bakelite sheets are used for separating high tension and low tension windings. The high voltage transformers used for HV cable testing also need to supply sufficient electric current.
This can generate a lot of heat, and as such the cooling system of these transformers is very carefully designed. Special care also needs to be taken to ensure proper transformer voltage regulation.
For insulator testing purposes, the required current is very less but, while the insulator breaks down during testing, there would flow huge current through the transformer. To limit this current, a high resistance is connected in series with transformer.
