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
1) Suitable to measure currents from A to hundreds of kA.
2) High linearity.
3) The absence of magnetic core grants a wide frequency response to be suitable for measurement of harmonic
content and transients.
4) Very useful with large size or awkward shaped conductors or in places with limited access.
5) Non-intrusive, no power drawn from the main.
6) Not damaged by large overloads.
7) There is no danger from open-circuited secondary.
Applications
1) Very high current monitoring
2) DC ripple measurement
3) Harmonics and transients monitoring
4) Power monitoring & control systems
5) Applicable in eletronic Watt-hour meter
6) Power quality monitoring
7) Electric furnace
8) Harmonic management
9) Relay Protection
