Abstract A new test method for internal PD resistance of insulating materials has been studied intensively by a task force at CIGRE for over ten years. Recently, Method II, which was developed by the authors, is now being studied as the international round robin test proposed by a domestic task force. This paper describes the new test method concretely and shows some typical test results. The test electrode system is characterized by adhesion of test specimen to the embedded sphere electrode, and it may be applicable to all sorts of insulating material for the internal PD resistance test under uniform partial discharges. The most important point of this method is to realize the complete adhesion by skillful techniques. It was ascertained that the spread of test data may depend only on the uniformity of materials by this method, and excellent life data can be obtained for some specific materials.
