A fiber-optic current sensor (FOCS) is a current sensor for measuring direct current. By using a single-ended optical fiber around the current conductor that utilizes the magneto-optic effect (Faraday effect), FOCS measures uni- or bidirectional DC currents of up to 600 kA within ±0.1% of the measured value. Because it does not need a magnetic yoke, an FOCS is smaller and lighter than Hall effect curren… WebSensor electronics. IP 00, always to be mounted in a control cubicle: Optical fibers. IP 67.
