Abstract :
Various applications of optical current and voltage sensors are explored. Wide bandwidth, linearity, high accuracy, and light weight of these sensors make this technology suitable for numerous applications: high-accuracy wide dynamic range revenue metering, regular protection applications, capacitor bank unbalance protection (low ratio CTs), current measurement in HVDC systems, and power quality monitoring including measurement of harmonics near static VAR compensators and fast transient measurements. The fiber optic CT with a unique flexible head packaging (rope-shaped wrap-around sensor head) has novel application in generator monitoring and protection. Due to their light weight and ease of deployment, both the flexible-head optical CT and the optical VT are great tools as portable calibration systems for live in-situ calibration and monitoring applications
