DETECTION OF FAULTS IN THE INSULATION OF AN ELECTRICAL CONDUCTOR Abstract of the Disclosure Faults, such as pinholes, in the insulation of an electrical conductor are detected by passing the conductor through a liquid electrolyte which acts as a liquid electrode. A regulated DC supply is connected to the electrolyte, the conductor core grounded, and the DC bias to the electrolyte monitored. Any variation in the DC bias, is detected and for any change over a predetermined minimum value a signal is produced, which can be used to actuate a marker or stop the line. More than one conductor can pass together, for example twisted pairs or quads as used for telecommunications.
