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 […]
Surge protector, also known as lightning arrester, is an electronic device that provides safety protection for various electronic equipment, instrumentation, and communication lines. When a surge current or voltage is suddenly generated in an electrical circuit or communication line due to external interference, the surge protector can conduct the shunt in a very short period […]
Surge Protection Devices (SPD) are used for electric power supply networks, telephone networks, and communication and automatic control buses. The Surge Protection Device (SPD) is a component of the electrical installation protection system. This device is connected in parallel on the power supply circuit of the loads that it has to protect (see Fig.1). It […]
