What is the basic principle of SPD remote signal terminal and how does it achieve communication? Dec 11 , 2025
The remote signal terminal of the surge protection device is the key interface for remote monitoring of the SPD status. Its core function is to convert the SPD operating status (such as normal, faulty, tripped, etc.) into a transmittable electrical signal and transmit it to the remote monitoring system (such as the distribution automation system, computer room monitoring system, etc.), thereb...

What is SPD energy coordination? Dec 17 , 2025
The so-called energy coordination means that when multiple levels of SPDs or protective elements have different discharge capacities and are used together, the lightning current must be reasonably distributed to ensure that the SPDs or elements with smaller discharge capacities are not damaged. As shown in the figure below, SPD1 has a high discharge capacity and a high residual voltage, while SPD2...

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...
