Surge arrester aging is invisible until failure — by the time degradation is evident, catastrophic failure may be imminent.

Lightning strikes that reach substation equipment unimpeded can destroy transformers worth millions of dollars in a single event.

Lightning arresters lacking status monitoring will silently fail at critical moments. This article introduces diagnostic testing methods for leakage current, resistive current components, etc., to achieve predictive maintenance.

MCOV、 Rated voltage TOV、 Energy absorption capacity - These parameters determine the protection level of the lightning arrester. This article interprets the meaning and application scenarios of each rated value one by one.

Improper installation can cause the correctly selected lightning arrester to lose its protective function. This article provides a detailed explanation of key practical points such as installation location, grounding requirements, and clearance distance.

The failure modes of zinc oxide lightning arresters include various forms such as thermal breakdown and aging degradation. This article analyzes the root causes of common faults and provides diagnostic and preventive measures.

The choice of material for the lightning arrester casing directly affects the equipment's lifespan and maintenance costs. This article provides an in-depth comparison of the performance differences, hydrophobic properties, and full lifecycle costs between silicone rubber and ceramic shells.

Choosing the wrong lightning arrester can result in equipment damage during the first overvoltage event. This article discusses system voltage MCOV、TOV、 Based on key indicators such as energy absorption capacity, provide systematic selection of lightning arresters.
