System for high voltage current transformers onsite verification

This paper presents a solution for high voltage current transformers onsite errors verification, using a system composed by an optical current sensor 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.
