 Flexible Rogowski Coil


Flexible Rogowski coil split core 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.

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

Features:

1. Flexible and lightweight

2. Coil length from 20cm to 100cm

3. AC current probe utility by the Rogowski principle

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
