This document specifies the method for determining the dielectric breakdown voltage ofinsulating liquids at power frequency. The test procedure is performed in a specified apparatus,where the oil sample is subjected to an increasing AC electrical field until breakdown occurs.The method applies to all types of insulating liquids of nominal viscosity up to 350 mm2/s at40 °C. It is appropriate both for acceptance testing on unused liquids at the time of their deliveryand for establishing the condition of samples taken in monitoring and maintenance ofequipment.
