A SPD must always be installed at the origin of the electrical installation. Location and type of SPD The type of SPD to be installed at the origin of the installation depends on whether or not a lightning protection system is present. If the building is fitted with a lightning protection system (as per IEC […]
Surge protective decives, also known as lightning arresters, are electronic device that provide 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 lines due to external interference, thesurge protective decives can conduct the shunt in a very short period of […]
