Now SPD monitoring has gone far beyond simple "on/off" indications. What intelligent directions is it developing towards? Mar 12 , 2026
Traditional SPD monitoring only provides a dry contact signal based on a mechanical disconnector, which is a typical "post-failure alarm"—it informs the user that the SPD has completely failed and needs to be replaced. Modern intelligent monitoring modules, however, utilize built-in microprocessors and sensors to transform the SPD from a passive protection component into an intelligent node capabl...

For SPDs used in high-altitude areas, the electrical clearance needs to be increased. How does the GB/T 18802.11 standard reflect this requirement in testing and certification? Apr 28 , 2026
The GB/T 18802.11 standard explicitly acknowledges the influence of altitude on electrical clearance insulation strength and incorporates this through an "altitude correction factor" in the testing conditions. The standard typically uses 2000 meters as the baseline altitude. For surge protective devices (SPDs) claimed to operate normally at higher altitudes (such as 5000 meters), the testing requi...

Jinli Electric: Lightning arresters and surge protective devices safeguarding the safety of medium- and low-voltage power distribution systems. Sep 16 , 2026
During thunderstorms, lightning-induced surges and switching overvoltages can easily penetrate equipment such as box-type substations and ring main units, damaging insulation and causing power outages—resulting in economic losses for industrial parks, new energy projects, and mining operations. As a core protective component, the surge arrester clamps overvoltages and dissipates surge energy, ther...
