Failure of electrical and electronic systems are due to insulation breakdown or when over voltages exceed the equipment’s insulation withstand level. Equipment is protected if its rated impulse withstand voltage UW at its terminals is greater than the surge overvoltage.
Coordinated SPD’s installed in the electrical system provide protection against conducted surges. Shielding and Routing of power and data lines, Bonding of Services at various Lightning Protection Zones (LPZ) & Earthing plays major role in protecting electrical and electronic equipment from radiated surges
SPD shall be selected according to their environmental conditions and the acceptable failure rates of the equipment and the SPD”s
SPD’s for power line need to be installed according to the type of Service such as TN, TT, IT etc. Two type of connections are recommended which need to be selected based on type of network, place of installation, Temporary over voltage conditions etc.
Surge protection for data and signal line systems provide unsurpassed electrical protection for signal power applications. These products meet the diverse requirements of industrial and other signal protection applications. Data Line surge protection products are available in a variety of operating voltages and configurations that conform to the latest industry standards and certifications.
