查询词典 impedance

For reducing the LEMP lighting electromagnetic pulse radiation, the electrical source uses the Box-type power supply arrester, the power supply arrester and the modular power supply arrester as the third SPD surge protection device. The Low-voltage surge arrester or spark gap is laid between the compute net and equipotential grounding grids for avoiding signal interference and counterattack of ground voltage. The parameter and model of the signal lighting-protector of lines of communication are chosen according to the transfer rate, work level and characteristic impedance.
