Surge Protective Device BKS SP series 34 Considerations during installation SPD shows the difference in performance depending on the installation method Therefore SPD is installed in consideration of the following matters 1 Protection and installation method If SPD with sufficient surge rating is installed in the location close to the entrance of the distribution board for various wiring systems when the device or facility to be protected has sufficient overvoltage rating most facilities can be protected 2 Shuttle vibration phenomenon If the device or facility to be protected is distant from SPD the voltage that is about 2 times higher than the SPD limiting voltage is generated in the facility to be protected by the shuttle vibration of the incidence surge The shuttle vibration of surge can be disregarded in case of the 10m or shorter wiring length but the twofold or higher voltage can be generated in case of the 10m or shorter length so that the cooperation between the protection element inside the device or facility to be protected and SPD should be well accomplished 3 Length of the connection line In order to most effectively protect the overvoltage it is necessary to shorten the length of the connection line for SPD wiring and to apply the wiring method restricting the induced voltage of the inductance of the connection line 4 Necessity for additional protection If the lightning surge voltage flowing into the de
