  • Abstract
    The paper describes a new method of estimating thermal breakdown in EHV oil-impregnated paper-insulated cables with some experimental data. In the analysis it is shown with the computed results that the heat generation in the insulation can be exactly approximated by the average temperature of the insulation. In addition this method can calculate the critical voltage at which EHV cables go into thermal breakdown. The values here calculated compare agreeably with the breakdown voltages of 500 kV OF cables.
