  • Monitoring of electrical insulation integrity
    Patent number: 4301399
    Abstract: The integrity of the insulation of an electrical device composed of at least two conductive members having a potential therebetween and at least two insulating layers successively surrounding the conductive members, is monitored by interposing an electrically conductive, integrity monitoring layer between the two insulating layers so that a first one of the insulating layers is disposed between the conductive members and the conductive layer and a second one of the insulating layers is disposed between the conductive layer and the environment surrounding the device, monitoring the impedance of the first layer between the conductive members and the conductive layer, and monitoring the impedance of the second layer between the conductive layer and the surrounding environment.
