Devices Surge Protection (SPD) are designed to protect electrical and electronic equipment against pulse overvoltage surges (lightning and switching) and performs two main tasks: Limit the surge voltage to the required level, Taps surge current to the ground. SPDs Type 2 are designed for safe ground-fault current pulses at a remote lightning strikes or when switching the power supply system. They are not designed to protect against direct lightning strikes as device type 1, but compared with them provide a lower level of voltage protection. SPD Type 2 is recommended to be installed on the input electrical installations, for which there is no danger of a direct lightning strike, or to use as a second stage of protection after installing Type 1 devices.
