Insulating liquids. Determination of the breakdown voltage at power frequency. Test method Ingestion-build-44616 6 (Test pieces machined from1 Scope This International Standard specifies the method for determining the dielectric breakdown voltage of insulating liquids at power frequency. The test portion, contained in a specified apparatus, is subjected to an increasing a. c. electrical field by means of a constant rate of voltage rise until breakdown occurs. The method applies to all types of insulating liquids of nominal viscosity up to 350 mm2s1 at 40 C. It is appropriate both for
