Recent Progress of All Fiber Optic Current Transformers
Jianhua Wu, Xiaofeng Zhang
Abstract
All fiber optic current sensors can overcome the shortcomings of traditional electromagnetic current transformer in volume, weight, safety, environmental protection, dynamic range and so on. It has broad application prospects in high voltage, ultra-high voltage applications and smart grid. This paper discusses the research status of all fiber optic current sensors at home and abroad, introduces the basic working principle and the evolution process of optical structure, emphatically analyzes the existing problems and solutions, and finally introduces the future development direction.
