RCTI-3ph Series

The RCTi is a current transducer for permanent installation. Simple to install and easy to retrofit, the Rogowski (sense) coil is thin, lightweight, flexible and clip-around. The secondary output from the transducer is an instantaneous voltage proportional to the measured primary current providing an accurate, low cost, wide-band measurement of the primary current. The RCTi is typically used with power and harmonic meters and analyzers, current meters, oscilloscopes, data-loggers, data acquisition cards, and in power quality applications.

Features:

  • Easy to retrofit
  • Simple to install in applications where space is limited
  • Non-intrusive - no power drawn from the primary circuit
  • Wide-band up to 1MHz, to measure harmonic components or complex waveforms (e.g. induction heating, VF drives, power measurement
  • The size of the Rogowski coil can be specified independently of the primary current
  • Does not suffer from magnetic saturation
  • Intrinsically safe
  • Equivalent to Class 1 CT or better
  • Low cost monitoring for medium/large currents.
