The surge protection protects the important electric installation and the information system equipment,prevents the atmospheric overvoltage and the switching surge,guards against the lightning to hit suppose the antimine device the building or neighbour the power source coil in place and so on the power source connections and guardagainst the thunderstroke electromagnetic pulse the protection.It's clear about in each kind of situation to bear the striking potential category and bore when the striking potential the rated value.The surge protector(SPD) in the electrical system establishment and the voltage protection level,passing current ability,the choice method and wraping between SPD the sychromesh are expounded.
