fiber optic current sensor / clamp / DC
ABB Motors Drives and Power Electronics
The Fiber-Optic Current Sensor FOCS measures DC currents easily with highly accurate fiber optic current sensors that are specifically made for testing high dc currents. With easy and flexible technical characteristics. Has a magneto-optic effect or faraday effect in a single ended optical fiber around the desired conductor, the FOCS is able to measure unidirectional or bidirectional DC currents of up to 500 kA with 0.1% measured value. It guarantees quick and easy installation, assembly and transport with high resistance to electromagnetic disturbances due to optical measurement. It also gives precision and plant efficiency calculation that ideally fits any environment.
