Tóm tắt

The dielectric breakdown testing of insulation liquids has a history of around 40 years. Special demands like the measurement of silicon oils requires the continuous improvement of testing equipment. Several experiments have led to the recognition of how important careful device design is in the reduction of the influence of the test procedure itself on the specimen.
