Troubleshooting T/R Sets

A common question when troubleshooting precipitator problems, especially when the focus is on the high voltage control system, is whether or not the transformer-rectifier set is operating properly.

What is a transformer rectifier set? Commonly called a œT/R set, the transformer rectifier is made up of a transformer (to step up normal service voltage (V) to the required kilovolt (kV) range) and a rectifier (to convert the high AC voltage to a direct current (DC) voltage supply). The T/R set is part of the precipitator electrical circuit, which consists of the service power supply, a modern voltage controller, a current limiting reactor, the T/R set and finally, the precipitator electrodes.
