RCTI-3ph Series

RCTI-3ph is a three-channel current sensor equipped with a thin, light, flexible, and clamp-on Rogowski coil. It provides very good current measurement accuracy in a wide frequency band. The output signal from the transducer is an instantaneous voltage value proportional to the measured current. The RCTi-3ph series is dedicated to applications using power quality measurement and analysis, as well as its harmonics. Furthermore, it is used as a cooperating device with all types of oscilloscopes, recorders, and data acquisition cards.

Key features

Easy to integrate                                   
Extremely simple to mount and easy to integrate into existing infrastructure.		 Simple installation
Flexible, thin, and light coil, extremely simple to mount

Accurate measurements
Precise power and energy measurements. Small phase error at 45/65Hz corresponds to accuracy class 0.5 for current transformers.

 Wide bandwidth – up to 1 MHz
enables measurement of harmonic components or complex waveforms.
Cable length selection
Longer cables than standard 1m and 2.5m are available – upon request.		 Custom coil length
Coils longer than the standard 300mm, 500mm, 700mm, and 1000mm are available upon request.



Properties

  • 3 measurement channels
  • non-invasive – no energy is drawn from the tested circuit;
  • each device is supplied with a calibration certificate
  • no magnetic materials means excellent linearity <0.1%
  • fully isolated measurement (2kVrms power supply, 2kVpeak coil)
  • DIN rail mounting
  • meets standards: CE, EMC EN 61326-1 2006, IEC 61010-1, IEC 61010-2-032
