The MOCT system satisfies current sensoring needs for revenue metering or protective relaying in a wide variety of applications.
Our passive optical current transducer uses light to accurately measure current on high voltage systems. It is suitable for outdoor application and has an accurate metering current range from less than 5 A to 2000 A using the same sensor. Metering accuracy exceeds class 0.2 per IEC 60044-1 over a wide metering range. For relaying applications, the system provides accurate waveform reproduction through 100 kA.
