Abstract :
This report deals with a study of the method for evaluating DC performance of dielectric materials using space charge and DC leakage current measurement. Two types of sheet specimens were prepared for space charge measurement, that is, simple specimens and sandwiched specimens. The simple specimens gave some information on space charge behavior. On the other hand, the sandwiched specimen made it easy to compare properties of two materials on space charge. Film specimens were used for dc leakage current measurement. Insulating materials may be evaluated in view of space charge behavior using this method
