<p>A multiconductor cable testing apparatus comprising a plurality of pairs of terminal connectors for connection to the ends of a corresponding plurality of conductors to be tested, and a test voltage source in series with each of said pairs of connectors. A corresponding plurality of normally open first contacts are each connected in series with a corresponding one of the pairs of terminal connectors. Furthermore, a corresponding plurality of first impedances are each connected in series with a corresponding one of the pairs of terminal connectors. Second impedances are connected in series with each of the first contacts. A corresponding plurality of normally open second contacts are arranged for applying a reference potential when closed, to one terminal connector of a corresponding one of the pairs of terminal connectors. Also incorporated in the testing apparatus is a voltage sensor for sensing the voltage across the second impedance.</p> |
