Compared with leakage current threshold value as defined in the leakage current value on survey time road and standard, so that it may which judging the insulation performance of test product is
No to comply with standard, after test, test voltage must gradually be down to zero before the deadline.
For some electrical appliances as tested in the cold state, the result measured does not have reference role to the operation of motor at all.Example
It is fever as motor operates normally all, in hot and cold conditions, the withstanding voltage of insulated paint is that there is a big difference.One
As high-power motor stator temperature can be close to 100 degrees Celsius, it is necessary to that does under hot is just of practical significance.
