摘　　要：给出了利用单片机串行通讯对电力系统 CT二次侧电流进行远距离数字传送和接收的实用方法 ,使CT不会因二次侧开路而烧毁 ,抗干扰能力强、测量精度高 ,并能够直接提供 A/ D转换结果。本装置已应用于电力参数微机监控系统中 ,电压和电流测量精度达 0 .2级。A practical method of remote figure transmitting and receiving for pow er system CT quadratic side current is given, which utilizes serial communicatio n of monolithic microcomputer. The method prevents CT from being burnt down by q uadratic side open circuit, has high noise proof features and high accuracy in m easurement and directly provides A/D converting results. The apparatus has been used in microcomputer monitoring system for power system parameters,with its acc uracy in measurement of voltage and current being in rating of 0.2.
