RCTi Series

RCTI is a current sensor equipped with a thin, lightweight, flexible, and fastenable Rogowski coil. It provides very good measurement accuracy over a wide frequency band. The output signal from the transducer is an instantaneous voltage value proportional to the measured current. The RCTi series is dedicated to applications involving the measurement and analysis of electrical power quality and its harmonics. Additionally, it is used as a device cooperating with various types of oscilloscopes, recorders, and data acquisition cards.

Key Features

Easy to integrate
Exceptionally simple to install and easy to integrate into existing infrastructure.		 Simple installation
Flexible, thin, and lightweight coil, exceptionally
easy to install


Control and monitoring
Ideal for process control and alarm state signaling

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



Properties

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