Application Sharing: Selection, Installation, and Maintenance of Surge Protection device Dec 25 , 2025
Sudden electrical malfunctions, unexplained equipment damage, and even occasional electrical fires are often related to "transient overvoltages," commonly known as "surges." These invisible "electrical shocks" can be caused by lightning strikes, turning appliances on or off, or interference from the power grid, making them "invisible killers" for electrical equipment. Surge protection device ...

What is the "clamping voltage" of SPD? What is the core role in SPD, and how it related to the "voltage protection level"? Feb 05 , 2026
The clamping voltage is a dynamic performance parameter, specifically referring to the peak voltage across the terminals of a surge protective device (SPD) when its core nonlinear element (such as a metal oxide varistor (MOV) or avalanche diode (TVS)) conducts and discharges a surge current of a specific waveform and amplitude. It is essentially the highest voltage established by the SPD during th...
