Abstract

Method for controlling the voltage UF of an electrostatic separator at the breakdown limit. This method involves, starting from an optimum number of flashovers per unit time Dsn and a set target voltage UZF, determining a subsequent operating time tB which is subdivided into n time intervals DELTA ti, the following relationships holding good: <IMAGE> The voltage UF is increased up to the breakdown limit, immediately after the time interval DELTA ti has elapsed, if it is true that D<*>i = 0. <IMAGE>
