Abstract

A detector for detecting breakdowns on the high-voltage side of an electric precipitator, the voltage of which is supplied from an a-c network through a thyristor control circuit, a high-voltage transformer and a rectifier. The improvement of the invention comprises means for continuously comparing characteristic parameters of successive half-waves of variations of the voltage at the precipitator. A predetermined deviation of the characteristic parameters comprises a criterion for determining a breakdown of the precipitator voltage.
