Abstract :
This paper presents a solution for high voltage current transformers onsite ratio and angle errors measurements, using a an optical current transducer with fiber sensor, based on Faraday effect as reference standard, suitable for live line installation up to 550 kV. The system is described; its performance results are presented, as well as field applications and results. Some limitations that have to be overcome to obtain a reasonable measurement uncertainty are also discussed.
