Abstract
A device for checking the insulation of the leads connecting a power generator to a receiver. The receiver is sensitive to d.c. signals having an amplitude above a given threshold. A first output of an interference generator is connected to the first lead via a current detector and a resistor. A second output of the interference generator is connected to the second lead via a checking generator transmitting a.c. signals and a resistor. The current detector is sensitive only to a.c. signals transmitted by the checking generator.
