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.
1) AC current probe utility by the Rogowski principle
2) Flexible and lightweight
3) Coil length from 20cm to 100cm
4) Suitable to measure currents from mA to 100kA
5) Easy & quick installation in uninterruptible power line
6) Simple to install in applications where space is limited
7) The size of the Rogowski coil can be specified independently of the primary current
8) Does not suffer from magnetic saturation
