1. Report referee: the test is ready, the request begins

2. Enter the test site, check the electricity (first check the electric bar first), discharge (hang the ground wire)

3. Check whether the environmental conditions meet the requirements, record the laboratory temperature and humidity (fill in the actual temperature and humidity, keep one decimal place), report the referee: the environmental conditions meet the verification requirements.

4. Visually check according to the rules, record the nameplate parameters, and report to the referee that “intuitive inspection is acceptable”.

5. Determination of insulation resistance. Discharge the insulation resistance before each measurement. Turn off the megohmmeter after the measurement is completed.

6, power frequency voltage test (not specific operation). According to the requirements of the regulations, the results will be reported to the referee: the power frequency withstand voltage test is qualified, and the power frequency voltage is applied at 95kV for 1 minute, and there is no breakdown or flashover phenomenon.

7, wiring. First ground wire, then connect the low-voltage side cable, then the high-voltage side cable, and finally the power cable. Note: It is not allowed to step on the wire during the wiring process; the same terminal wire should not exceed three wires; the same terminal wire should be the same color wire.

8. After the wiring is completed, the site is cleaned up, and the referee is reported: the wiring is completed and the application is closed.

9. Winding polarity check. Error measurement Simultaneously check the winding polarity, increase the voltage to 5%-10%, check the polarity of the winding, report the referee: the polarity check is qualified, and the polarity is reduced.

10. Error measurement. Adjust the test point to deviate from the specified value by 0.5%

11. Reporting completion report: After the test is completed, apply for the line. Enter the site to check the electricity first, then discharge. When disconnecting the line, first remove the power cord, then remove the high voltage side, then remove the low voltage side, and finally remove the ground wire.

12. Verification of the original record, verification certificate or verification result notice

13. After the competition is over, test instruments, instruments, tools, test lines are restored, and the site is cleaned.
