②因为辅助绕组的一端与b相接地点相连,由于基本二次侧绕组上有负荷电流流过,在电缆芯出上产生电压降,使正常开口三角形有电压3U0,对零序方向元件不利。若单独从接地点引接零序方向继电器回路,则接线较为复杂。在中性点接地系统中,由于中性点无任何断开触点,可靠性高。 [1] 各种电流表的量限、使用频率范围及可能达到的最高准确级见表。波形非正弦对电磁系、电动系、热电式电流表影响较小。整流式电流表限定用于正弦波形下,数字电流表也有类似限制。电力系统中为测非正弦电流可采用变换器式电流表。

(2)电动机供电回路三相熔丝规格不同,容量小的熔丝烧断。应根据电动机功率大小,更换为规格相同的熔丝。(3)电动机供电回路中的开关(隔离开关、胶盖开关等)及器的触头不良(或松脱)。修复并动、静触头,使之良好(4)线路某相缺相。 (4)当q和v┴改变时,F┴的大小也改变,但比值F┴/(qv┴)在任一点总是常量,显然,该比值反映了磁场在该点的性质,与运动试探电荷无关,我们可利用该比值来定义描述场本身特性的物理量磁感应强度矢量B。在本章中,也要引入场的概念,后给出产生场的规律。
