Abstract
XLPE insulated power cables are used for transmission and distribution of electrical power in urban centers. Extensive high voltage testing is conducted on such cables for performance evaluation and quality control purposes. During such testing, the cable ends have to be prepared carefully to make a proper end termination. Usually deionized water terminations are used for this purpose. Alternatively conductive paint is used to prepare a resistive termination. This paper discusses a method of calculating the voltage distribution across such a resistive termination when subjected to impulse high voltages. The proposed method is used to determine the effect of different design parameters on the impulse stress distribution of such cable ends.
