Clamp-on Flexible Rogowski coil Current Transformer is an AC current transducer for permanent installation.
They combine the benefits of a thin, flexible, clip-around Rogowski (sense) coil with a signal conditioner providing
accurate, true rms measurement, of voltage or current.
Features
High linearity from 1A to 100kA
Wide dynamic range
Very useful with large size or awkward shaped conductors or in places with limited access
No danger from open-circuited secondary
Not damaged by large overloads
Non-intrusive,no power drawn from the main
Measurement uniformity at any position of the conductor inside the coil
Excellent degree of rejection to the external current conductor
Applications
Measuring devices,lab instrumentation
Power monitoring&control systems
DC ripple measurement
Harmonics and transients monitoring
Power meter,Powe ranalyzer sensor
