Arrangement for detecting dielectric breakdowns in metal-clad high-voltage switching and transmission installations

摘要

An arrangement for detecting dielectric breakdowns in high-voltage installations with several gastight, compartmentalized sections includes at least one stationary measuring device at the section wherein a fault can occur. The measuring device is connected with an evaluation control arrangement for operation in combination therewith. The measuring device is an electroacoustic transducer which picks up the sound waves generated at the breakdown point and is connected with the control arrangement through frequency and amplitude dependent filters.
