Surge Protection Devices
Frequent lightning surges can damage electrical and electronic systems by causing insulation breakdown or when the voltage gets too high for the system to handle. To protect equipment, its rated impulse withstand voltage (UW) should be higher than the surge voltage between the live wires and the earth. If not, a Surge Protection Device (SPD) should be installed. These systems must follow IS/IEC 62305 and NBC 2016 standards.
Using coordinated SPDs helps protect against surges. It’s also important to properly shield and route power and data lines, bond services, and set up Lightning Protection Zones (LPZ) and proper earthing for safety.
SPDs protect electrical systems and equipment from overvoltages and surge currents caused by lightning and switching. When choosing an SPD, consider the environmental conditions and acceptable failure rates for both the equipment and the SPD.

SPD for Power Lines
SPDs for power lines must be installed according to the type of service, such as TN, TT, or IT systems. Two types of connections are recommended, and the choice should be based on factors like the type of network, installation location, and temporary overvoltage conditions.

SPD for Data Lines
Surge protection for data and signal line systems offers exceptional electrical protection for signal power applications. These solutions cater to the varied needs of industrial and other signal protection uses. Data line surge protection devices are available in a range of operating voltages and configurations, all of which comply with the latest industry standards and certifications.
