EHV power sources
EKO and EMO electrostatic precipitators are powered by direct current from sources of extra high rectified voltage (EHV).
EHV power source characteristics:
- single-phase quartz rectifiers with a high voltage
transformer and measuring circuitry - single-phase quartz rectifiers with a high voltage
transformer connected with a pulse generator and measuring circuitry - three-phase quartz rectifiers with a high voltage
transformer with a switched high frequency converter and measuring circuitry
Material preparation room
