In three phases and four wires system,all three phase lines and one neutral line to earthing line have SPD to be protected,in normal service,the SPD in at the state of high resistance,when network produce surging overvoltage due to thunder or other reasons,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 of network.
1.Surge protection device to be installed in a standard rail.
2.The SPD need not to be adjusted after installed according to requirement.
3.It can automatically protect the power network after proper installation.
4.SPD is invalid or not,meanwhile check if indicator if fuse lighting or not,please replace the invalid element on time.
