LYD1-B 80 SPD In three phases and four wires system, all three phase lines and one neutral line to earting line have SPD to be protected, in normal service,the SPD is at the state of high resstance, when network produce surging over-voltage due to thunder or other resons, SPD will be conductive within short time(ns),lead surging voltage into ground,consequently to protect the electric appliances of network. After surging voltage passed by SPD,and disappeared, SPD recover in high resistance.It will not have influence on the normal service on network.
