Progress in All-Fiber Optical Current Transformer Technique
Qisheng Wang · Laser & Optoelectronics Progress · 2005
The classification of current transformers and the principle of all-fiber optical current transformers are introduced. The solutions for the problems induced by liner birefringence and the fluctuation of the Verdet constant etc in all-fiber optical current transformers are reviewed. In addition, the progress in othertyped optical current transformer, such as using magnetostrictive material and fiber gratings are also recommended.
