IEC 60243 Power Frequency Test for Electrical Strength of Solid Insulating Materials
Scope of application:
It is mainly suitable for continuous and uniform step-by-step step-up, applying AC/DC voltage to the specimen until breakdown, measuring the breakdown voltage value, and calculating the breakdown strength of the sample; Use the method of rapid voltage increase to raise the voltage to the specified value, keep the sample without breakdown for a certain time, and set the specified value at this time as the withstand voltage value of the sample.
