Surge protection devices (SPD) and surge arresters have the same function: they can protect electrical equipment from overvoltage conditions, but what is the difference between them? The following is a brief description of the differences between them. 1. Different Rated Voltages: According to NEC 2017 Sec 280 & 285, the rated voltage of the surge […]
As we know, surge protective devices (SPDs) play a critical role in protecting electrical systems from power surges and spikes. When the visible windows is turned to be red, it means the surge protective devices (SPDs) are broken. What are the factors that cause surge protective device (SPD) to break? 1. Overvoltage Conditions Surge protective […]
