1. Requirement Introduction
Surge Protection Device (SPD) connected in the mains power supply, needed to protect the
electrical and electronic equipment, should be able to withstand maximum of 100 kA per mode
(10/350sec).As per IEC 62305-1, LPL 1 (Lightning Protection Level) maximum expectedlightning current is 200 kA. As explained in IEC 62305,100 kA will be dissipated in earth and
the balance 100 kA will reach the electrical supply lines. Power Line SPDs are to be connected at
the mains incoming panel and in addition Distribution Boards which are more than 15 meters
away from the incoming panel. DBs which is feeding power to critical and sophisticatedelectronic equipment. SPDs must be installed ignoring the cable distance. Suitable SPDs also tobe used in all Telecommunication, Signaling, automation and instrumentation equipment
according to the Zonal concept explained in IEC 62305 for a perfect protection of complete
electronic installations. All SPDs should be tested and ensure performance requirements
according to IEC 61643
