浪涌抑制与电磁兼容 浪涌抑制与电磁兼容 SURGE SUPPRESSION AND ELECTROMAGNETIC COMPATIBILITY MO Fu-jiang，RUAN Jiang-jun，CHEN Yun-ping (School of Electrical Engineering，Wuhan University，Wuhan 430072，Hubei Province, China)    ABSTRACT: Surges are the over-voltage and over-current phenomena thatoccur commonly in low-voltage AC power line. To research the surges in ACpower line, the voltage amplitude of surge should be analyzed and thecurrent and energy should be also analyzed. In the suppression of surges inlow voltage power lines the over-voltage protection measures and theelectromagnetic capability (EMC) of the electronic devices should beconsidered. Through the calculation of the waveforms and the baud chart ofstandard ……
