Alligator clip|What are the problems that should be paid attention to when using the anti-interference dielectric loss tester

Electricians who want to conduct dielectric loss tests on power transformers, relays, capacitors, arresters, etc. need to use an anti-interference dielectric loss tester. As a relatively conventional high-voltage power test equipment, this equipment has high voltage levels and reliable accuracy. And other advantages, but there are still many problems that need to be paid attention to in the process of use, so what are the problems that should be paid attention to when using the anti-interference dielectric loss tester?

1. Ground the instrument reliably to ensure that the shell of the instrument is at ground potential.
2. For positive wiring: insert the high-voltage cable plug into the HV socket of the instrument, clamp the black alligator clip at one end to the high-end lead of the tested product, and hang the red alligator clip in the air. Insert the Cx low-voltage cable into the Cx socket, the red clip at the other end clamps the low end or the end screen of the test sample, and the black clip is suspended or connected to the shielding device.
3. When reverse wiring: insert the high-voltage cable plug into the HV socket of the instrument, clamp the red alligator clip at one end to the high-end lead of the tested product, and hang the black clip in the air or connect to the shielding device. The Cx socket is not used.
4. Comply with the requirements of "Safety Work Regulations for High Voltage Tests".
5. The high-pressure test must be attended by more than two staff members, with one operating and one supervising.
6. After the wiring is completed, one person is responsible for the inspection.
7. After the test, turn off the power switch. It is strictly forbidden to disassemble or assemble the high-voltage cable with power on!
8. If the instrument is abnormal, turn off the power switch and wait for about one minute to check again.
9. After the measurement is completed, the power switch must be turned off, and the wires will be removed after waiting for about one minute.
