The dielectric strength test isTesting instrument transformerimportant content of insulation performance test. It is used to detect the damage ability of transformer insulation materials and product structures under the action of electric field, and to check the defects of insulation performance. In the test, in addition to the specified voltage resistance, there is also a leakage current requirement. From low power to high power supply transformers, the specified leakage current range is1mATo10mA.
The main technical requirements of transformer dielectric strength test equipment are: output voltage, capacity and alarm current. The current determined during the transformer dielectric strength test is actually the alarm current of the test equipment. When the insulation defect causes the current of the high-voltage test circuit to exceed the specified alarm current, the high-voltage test equipment will trip and issue an alarm to judge the insulation fault.
Because the transformer power is different, the size is different, the insulation capacitance is also different, so the leakage current of the transformer is not the same.
