    Abstract - (Show below) - (Hide below)

    Sets out the method for determining the dielectric breakdown voltage at power frequency, of insulating liquids of nominal viscosity up to 350 mm(sup)2(/sup)s(sup)-1(/sup) at 40 degrees Celsius. Intended for use of acceptance testing on new liquids and for monitoring the condition of liquids in use. This Standard is identical with and has been reproduced from IEC 60156:1995.

    Scope - (Show below) - (Hide below)

    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 mm2s-1at40 ¦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.
