Fiber-Optic Current Sensor FOCS Fiber-Optic Current Sensor FOCS--Fiber-Optic Current Sensor FOCS
Make light work of dc current measurement ABB's FOCS is a family of high accuracy fiber-optic current sensors developed for measuring high dc currents. The easy and flexible use characterizes this technical innovation. Based on the magneto-optic effect (Faraday effect) in a single-ended optical fiber around the current conductor, the FOCS can measure uni- or bidirectional dc currents up to 500 kA with an accuracy of 0.1 % of the measured value. The key product features can be described as: Compact design for fast and easy assembly, installation and transport Immune to electromagnetic interferences due to optical measurement and therefore no need of magnetic centering, busbar studies or subject to saturation effects which reduce the accuracy High accuracy of 0.1 % of the measured value for precise plant efficiency calculation No special building structure for the protection and housing of the sensor Optical current measurement for galvanic isolation of the system and low power consumption
