Flexible split-core AC current sensor implementing high accuracy Rogowski Coil technology
Main characteristics:
- Thin, light and flexible split-core current sensor for easy installation anywhere
- New Perfect Loop Technology for no-discontinuity coil clasp
- Better than 0.65% accuracy regardless of the primary conductor’s position
- Almost perfect linearity, no saturation, no upper limit in current rating
- 5% manufacturing tolerance (calibration required)
- Low output voltage proportional to the rate of change (derivative) of the primary current (electronic integrator required)
Features:
- 5 mm gauge with sensing apertures of Ø 55mm (RT 500) or Ø 125mm (RT 2000)
- Mass: 85g (RT 500) to 90g (RT 2000)
- Bandwidth: 50/60 Hz, up to 700kHz (RT 500) or 500kHz (RT 2000) in open circuit condition (no load)
- Isolation test voltage: 3.5kV RMS / 50Hz / 1min
- Operating range: -10°C to +65°C
Standard:
- The products are CE certified regarding their safety according to the European directive 2006/95/EEC and tested according to the standards IEC 61010-1.
- Using UL94-VO recognized materials
Remarks:
- First Rogowski coil suitable for Class 1 power monitors and energy meters
- The Perfect Loop Technology (Patent ref. WO 2009/001185 A1) definitely solves the problem of the Rogowski coil opening by introducing a specific magnetic device. This dramatically reduces both the error due to the position of the measured conductor within the sensor, and the error due to the proximity of external conductors.
