摘要
应用Faraday效应进行测量的电子式电流互感器,由于双折射和温度稳定性的影响,实用化进程缓慢.文中阐述了90年代以来电子式电流互感器发展的新趋势,例如应用铁氧体磁畴效应、磁流体热透镜耦合光磁效应等进行测量.这些电流互感器都克服了传统电子式电流互感器双折射效应的影响,具有良好的应用前景.
With the disadvantages of birefringence and temperature stability, conventional electronic current transformers with Faraday effect have some difficulties in practical applications. Since 90's some novel electronic current transformers have utilized various physical effects, such as domain wall motion in orthoferrites, thermal lens coupled magneto-optical effect in ferrofluid. These new electronic current transformers show good prospect in future practice.
