Contact monitoring circuit for high-voltage test systems compares end of shield or auxiliary wire with reference potential via semiconducting switch, displaying signal if potential difference exists

摘要

The circuit (0.1) has a shield or auxiliary wire of a signal line (2) to be monitored at one end of the signal line at reference potential and the other end of the shield or auxiliary wire is compared with the reference potential via a semiconducting switch and if there is a potential difference an indication signal can be generated by an operating and indication circuit (10) that can be visually represented on a display.
