H.V.Transformer for x-ray Generator

The transformer assembly has a low voltage filament transformer which is a step-down transformer, and a high-voltage step-up transformer. The transformer assembly also includes rectifiers for the high-voltage circuit.

Due to the high potential differences between the high-voltage circuit and filament circuit (up to 150 kV), the transformers and rectifiers are usually immersed in oil which serves as an insulator and prevents sparking
