Please refer to the test standard for details. The whole spring inspection test of substation is divided into characteristic test and insulation test.

Preventive Test Measures for Electrical Equipment in Spring

1, the insulation test is destructive, which is particularly important. Pay special attention to the selection of AC withstand voltage, as shown in the following table:

2. Test the integrity and accuracy of instruments and equipment, such as dielectric loss tester, insulation meter, line parameter tester, MSXB series resonant equipment, etc.

3. Professional level of testers
