FAQ

1)What is the core function of the MEYBJ-W Surge Arrester Counter Tester?

Answer: Its core function is to verify the reliability of various surge arrester counters' operations, providing power system personnel with critical data on lightning strike counts. This enables targeted inspection of surge arresters, ensuring stable operation of the power system.

2)What are the key wiring requirements when using the MEYBJ-W Surge Arrester Counter Tester?

Answer: Connect the instrument's output terminals to both ends of the surge arrester counter. Keep connection cables as short as possible. Connect the red terminal to the upper end of the counter and the black terminal to the ground terminal. Before wiring, confirm the test item is de-energized. After wiring, verify the instrument and connections are correct. Only disconnect after testing is complete and the output voltage fully returns to zero.

3)Why is the detection method used by the MEYBJ-W Surge Arrester Counter Tester recommended?

Answer: This instrument employs the standard impulse current method. Research indicates this method is the most reliable approach for field verification of counter operation. By generating an 8/20μs, 100A standard impulse current wave, it accurately identifies counter malfunctions caused by moisture ingress or internal component damage. This method complies with regulatory requirements and delivers highly credible test results.
