Fault detection device for detecting fault in discharge current path of high voltage surge arrester

摘要

A device which triggers off a drive mechanism (6) when an error occurs is provided in order to detect an error in a high voltage surge diverter. The drive mechanism (6) is triggered by an electrical signal. The electrical signal is produced according to the current which flows in the leakage path of the high voltage surge diverter. The inventive device can be, for instance, embodied as a high voltage surge diverter disconnecting device or as a failure signal device for high voltage surge diverters.
