Organization: IEC
Publication Date: 1 August 2018
Status: active
Page Count: 41
ICS Code (Insulating oils): 29.040.10
ICS Code (29.035.40): 29.035.40
ICS Code (Insulating fluids): 29.040
ICS Code (Other standards related to electricity and magnetism): 17.220.99
scope:

This document specifies the method for determining the dielectric breakdown voltage of insulating 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 at 40 °C. It is appropriate both for acceptance testing on unused liquids at the time of their delivery and for establishing the condition of samples taken in monitoring and maintenance of equipment.
