Fiber-optic current and voltage sensors are attractive alternatives to conventional measurement transformers. The dielectric nature of optical sensors makes them ideally suited for use on high voltage. They are of small size and weight, measure current and voltage with higher fidelity, offer higher safety of operation and environmental friendliness (e.g., no risk of oil spills). The digital sensor electronics is directly compatible with modern digital substation control and protection systems. Challenges are the stringent accuracy and reliability requirements in electric power transmission. Often accuracy is demanded within ±0.1 or ±0.2% for temperatures from -40 to 85°C. The talk gives an overview on the technology of optical current and voltage sensors and illustrates their applications.
