An automatic voltage control system for electrical precipitators

A FUNDAMENTALLY new system of precipitator automatic voltage control has been developed for use in the Cottrell process of electrically removing suspended matter from gases. The new system is based on extensive field measurements with respect to the actual operating requirements necessary to obtain fundamentally sound performance. This, coupled with flexibility in design, ensures that optimum electrical conditions for maximum collection efficiency will be maintained automatically and continuously for a wide range of precipitator conditions.
