Abstract
The electrical conductivity of thin oil-impregnated paper insulation at high electric fields¿> 100 kv/cm (kilovolts per centimeter)¿has been measured as a function of temperature and voltage. Assuming that the dominant part of the conduction takes place in the oil by means of ions, a theory has been developed which permits the approximate determination of mobility of the charge carriers¿10-9 to 10-6 cm2/v-sec (square centimeters/voltsseconds) between 35 C (degrees centigrade) and 145 C.
