ABSTRACT:
An arrangement for detecting dielectric breakdowns in a metal-clad, high-voltage installation made up of a plurality of component sections includes a thermal sensor for each of the sections wherein a dielectric breakdown may occur for sensing the temperature. The output of the thermal sensors feed a comparator which forms an output signal from at least two discrete signals from the thermal sensor. A circuit arrangement corresponding to the comparator identifies the thermal sensor associated with the component section wherein a dielectric breakdown has occurred.
