Abstract :
The properties of a dielectric for which the resistivity is an exponential function of electric field are examined. It is shown that such a dielectric exhibits a limiting electric field when applied to an AC system. The thermal characteristics of a small conducting stress enhancement in this system are examined to demonstrate thermal stability for power frequency applications
