三相异步电动机空载运行过程中，去测量电动机电流时，总会产生10%左右的电流差，一般有以下几个方面的原因:三相电源电压不平衡引起，但此时三相电压相差较小(一般小于0.5%)电动机磁路不均匀或三相绕组匝数不相等。如何判断空载运行电流差是电源电压引起的还是电动机自身引起的？1.通过调换三相电源线与电动机出线端的连接顺序，观察空载电流的变化。如果电动机电流大小的顺序随电源相序的变化而变动，也就是总是某一相电源的C相电流Zui大，则三相空载电流差是由三相电源电压引起的。
射频电缆按绝缘型式分类（1）实体绝缘电缆在这种电缆的内外导体之间全部填满实体高频电介质，大多数软同轴射频电缆都是采用这种绝缘型式。（2）空气绝缘电缆电缆的绝缘层中，除了支撑内外导体的一部分固体介质外，其余大部分体积均是空气。
