Electrostatic precipitators

Application

Power supply and control systems for the electrostatic precipitators (ESP) were designed to supply power and control applied voltage on the electrodes and to control functionality of the concomitant devices of the electrostatic precipitators

Primary features

• ESP voltage and current regulation or 
• regulation of number of sparks

Additional functions

• Opacity monitoring in function of power saving 
• Reduction of voltage at rapping 
• Reduction of voltage at starting/stoping of boiler
• Back corona detection
• ESP short circuit detection
• Current asymmetry detection

Operating modes of the automatic regulator

• Test, manual, continuous, intermittent
