HV Control Cubicles

Castlet HV Control Cubicles have provided reliable power and control of Transformer Rectifier units for Electrostatic Precipitators since 1974.

With the use of a thyristor regulator in the form of an inverse parallel pair, and our microprocessor based MCS III automatic voltage controller (AVC), the Control Cubicle provides full Transformer Rectifier control.
