1. The capacity selection of one time test transformer is applicable to the voltage regulation of test transformer with capacity below 100KVA.
2. The function of the current limiting resistor is to limit the open circuit current when the tested object breaks down, so as to protect the test transformer and prevent the expansion of the fault.
3. Power frequency withstand voltage test Test on the insulation resistance of electrical equipment to power frequency voltage.
The basic details of the power frequency withstand voltage test device in this article have been explained, and I hope it will be helpful to everyone.
