The FR125 Clamp Current Sensor is a portable, high-precision AC current converter featuring advanced CT technology and a large 125mm clamp opening for quick, convenient measurements. It provides safe non-contact measurement and can operate with a variety of instruments including electricity meter field calibrators, harmonic analyzers, multifunction meters, oscilloscopes, and double-clamp ground resistance testers. Designed for continuous energized environments, the FR125 enables accurate measurement of current, harmonics, phase, and energy parameters, making it ideal for substations, power plants, industrial sites, and electrical maintenance departments
