Electrical component insulation damage detection method, has test space filled with test gas having reduced breakdown voltage defined by test container surrounding tested component

摘要

The insulation damage detection method uses application of a test voltage and optical, acoustic and/or chemical detection of arcing within a test space enclosed by a test container, which is evacuated and filled with a test gas or test gas mixture with a reduced breakdown voltage compared to air before testing. An Independent claim for an insulation damage detection device is also included.
