IEC 60156:2024 PRV
Pre release version
Insulating liquids - Determination of the breakdown voltage at power frequency - Test method
Abstract
This Final Draft International Standard is an up to 6 weeks' pre-release of the official publication. It is available for sale during its voting period: 2024-06-21 to 2024-08-02. By purchasing this FDIS now, you will automatically receive, in addition, the Redline version of the final publication.
IEC 60156:2024 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.
