It is known that the efficiency of an electrostatic precipitation is concerned with the characteristic of applied effective voltage and corona current. This discharging characteristic is expressed a straight line on a log-log coordinate. Examining the slope of this line, the inside operating state of an electrostatic precipitation can be judged to improve on this efficiency. Cylindrical and square type corona-voltmeters to measure an applied effective voltage for an electrostatic precipitation were made. The characteristics of these voltmeters were considered and they were applied to practice electrostatic precipitation. The results are as follows. 1) Considering the practice field intensity and the discharging stability, the diameter of discharging wire for the cylindrical type corona-voltmeter (dia. 10cmφ) suits with 2?4 mmφ. 2) The discharging characteristics of these corona-voltmeters are composed of two straight lines, and authors call the potential of intersect point for these lines the starting corona voltage. Refering Peek's theorem and analyzing the wave forms of corona current, authors confirm the significance of the above assumption for practical use. 3) Their corona-voltmeters for the electrostatic precipitator (having three collecting rooms) in the cement factory of T Co. LTD. were used. As the discharging characteristic slope for the first collecting room is much larger than that for other collecting rooms, it is considered that this room is bad operating state. This cause is investigated and that is cleared away.
