Design of Prevention of the Electromagnetic Impuls for Thunderstruck
YE Haidong · Low Voltage Apparatus · 2002
In combination with a engineering for bank, the design of prevention of the electromagnetic impuls for thunderstruck and the selection of the surge protective devices (SPD) in the variety of distribution systems were introduced. The classification and parameters of SPD were analyzed and how to thinking about some parameters, such as the level of voltage protection, continual operating voltage, capacity of through current, residual voltage, protective models, response time and maintainability and service life etc. in the design were discussed. The method and requirements in the installation of SPD, including the connection, space and the cascade protection between SPD were discribed.
