High-voltage vacuum circuit breakers, owing to their excellent arc-quenching characteristics, suitability for frequent operation, and long maintenance-free intervals, have been widely applied in China’s power industry—particularly in urban and rural power grid upgrades, as well as in chemical, metallurgical, railway electrification, and mining sectors—and have received widespread acclaim from users.The primary advantage of vacuum circuit breakers lies in the vacuum interrupter. However, the char

Can dual-ended grounding be measured?Dual-ended grounding can be measured, but traditional high-voltage circuit breaker motion characteristic testers cannot perform such measurements. The conditions for dual-ended grounding are relatively complex; measurement accuracy must be ensured while simultaneously dealing with numerous electromagnetic interferences such as impedance and high-frequency currents. Therefore, a high-voltage circuit breaker tester specifically designed for dual-ended grounding
