Opticat current transformer
MOCT-P Optical Current Transformer System ABB Application : The Magneto-Optic Current Transformer for Protection (MOCT-P) is a passive optical current transducer which uses light to accurately measure current on high voltage systems. The MOCT-P system is suitable for outdoor application and has a continuous current rating up to 3150 A with an accuracy limit factor of 40 x. It meets the protection class accuracy 5TPE, according to IEC 60044-8. The electronic unit 2100-PI uses ABB’s patented dual-direction approach to make the output signal insensitive to shock and vibration. The optical design enables accurate reproduction of fully offset fault currents with decaying d.c. component without saturation or other source of distortion . Benefits of the MOCT-P Optical Current Transducer System : The MOCT-P system can satisfy current sensing needs for protective relaying in a wide variety of applications.
