ABSTRACT:
A testing apparatus for testing with D.C. and charging a cable. Through periodically switchable switching elements, like a switch-over or a switching rotor, the cable alternately swings via a choke coil and rectifier into an opposite polarity and re-swings again during the ensuing reswitching via a choke coil and rectifier into the previous polarity. As a result, the cable, after each switching break, is charged up to the original voltage by a testing apparatus with positive or negative polarity in order to compensate for the swing-over and current losses.
