Begär offert
An easy to use thin, flexible, clip-around Rogowski coil.
Since pioneering the wide-band Rogowski current probe over 30 years ago PEM Ltd have continued to develop the CWT, and now the shielded CWTHF, to provide state-of-the-art, wide-bandwidth AC current measurement.
The CWT combines an easy to use thin, flexible, clip-around Rogowski coil with an ability to accurately replicate fast switching current waveforms be they, sinusoidal, quasi-sinusoidal, PWM or pulsed.
Key Features
- For currents < 600A, or > 60kA the new CWTHF offers superior bandwidth and noise immunity.
- Models cover a range of 0.1Hz to 16MHz.
- Current ratings from 600A pk to 60kA pk.
- Peak di/dt 40kA/µs.
- Coil insulation 10kV pk.
- 8.5mm (max) coil cross section diameter.
- Loads the circuit under test by only a few pH.
- Standard coil length of 300mm to 1000mm, but longer coil lengths readily available.
Applications
- Current transient measurement in power electronic switching circuits.
- Lightning strike measurements.
- Power converter development and diagnostics.
- High frequency (hf) sinusoidal currents e.g. induction heating.
- Measuring small AC currents in the presence of large DC currents (e.g. monitoring capacitor ripple).
- EMC measurements, in traction, motor drives and power networks.
- Measuring fault currents, or currents in pulsed power applications.
