空心线圈往往由漆包线均匀绕制在环形骨架上制成，骨架采用塑料、陶瓷等非铁磁材料，其相对磁导率与空气的相对磁导率相同，这是空心线圈有别于带铁心的电流互感器的一个显著特征。（3）铁心线圈式低功率电流互感器（LPCT）。它是传统电磁式电流互感器的一种发展。其按照高阻抗电阻设计，在非常高的一次电流下，饱和特性得到改善，扩大了测量范围，降低了功率消耗，可以无饱和的高准确度测量高达短路电流的过电流、全偏移短路电流，测量和保护可共用一个铁心线圈式低功率电流互感器，其输出为电压信号。两者的使用发展方向由于电磁式电流互感器存在的易饱和、非线性及频带窄等问题，电子式电流互感器逐渐兴起。电子式电流互感器一般具有抗磁饱和、低功耗、宽频带等优点。

截止时间增加，这样可使得磁场电流平均值减小，磁通减小，保持输出电压不变。发电机的输出电压、磁场电流（平均值）随转速的变化关系称为电子调节器的工作特性。从电子调节器的工作特性曲线可以看出，为调节器开始工作转速，称为工作下限，随着发电机转速的升高，磁场电流减小。当发电机转速很高时，由于大功率三极管可不导通，磁场电流被切断，发电机仅靠剩磁发电，所以，电子调节器的工作转速上限很高，调节范围很大。[3]功能特点编辑采用移相触发方式，适用于阻性、感性负载，变压器一次侧。具有多种控制信号选择。具有“自动限流”功能，负载电流大于额定值时，调压器输出电流被限制在额定值左右。具有软起动、软关断功能，减少对电网的冲击和干扰。

退出有关保护，防止误动作。2.检查高、低压熔断器及自动空气开关是否正常，如熔断器熔断、应查明原因立即更换，当再次熔断时则应慎重处理。3.检查电压回路所有接头有无松动、断开现象，切换回路有无接触不良现象。[10]铁磁谐振编辑磁铁谐振的产生是在进行操作或系统发生故障时，由于铁心饱和而引起的一种跃变过程，电网中发生的铁磁谐振分为并联铁磁谐振和串联铁磁谐振。[11]主要特点1）对于铁磁谐振电路，在相同的电源电势作用下回路可能不只一种稳定的工作状态。电路到底稳定在哪种工作状态要看外界冲击引起的过渡过程的情况[10]。2)PT的非线性铁磁特性是产生铁磁谐振的根本原因，但铁磁元件的饱和效应本身也限制了过电压的幅值。

电机不断加速。当输出电压达到达速电压Ur时，电机也基本达到额定转速。软起动器在起动过程中自动检测达速电压，当电机达到额定转速时，使输出电压达到额定电压。限流起动：就是电机的起动过程中限制其起动电流不超过某一设定值（Im）的软起动方式。其输出电压从零开始迅速增长，直到输出电流达到预先设定的电流限值Im，然后保持输出电流I这种起动方式的优点是起动电流小，且可按需要调整。对电网影响小，其缺点是在起动时难以知道起动压降，不能充分利用压降空间。节能原理电动机属感性负载，电流滞后电压，大多数用电器都属此类。软启动器（图5）软启动器（图5）为了提高功率因数须用容性负载来补偿，并电容或用同步电动机补偿。降低电动机的激磁电流也可提高功率因数（HPS2节能功能。
