RIK 333mV Rogowski Integrator Kit

The Accuenergy Rogowski Integrator Kit (RIK) brings the convenience of a Rogowski coil current transformer to any power meter or device with a 333mV nominal current transformer input. The 333mV Rogowski integrator facilitates the installation of Rogowski coil CTs into a variety of applications where space constraints may limit the use of rigid-body current transformers. Highly adaptable, the seven user-selectable input ranges ensure the Rogowski Integrator Kit will be compatible with any system up to 60,000A AC. Available as either a three phase or single phase device, each kit includes flexible Rogowski coils in one of four standard lengths to pair with integrator.

  • 0-333mV rated output works with any power meter or device with 333mV nominal current transformer input.
  • Flexible, rope-like current sensor, designed to easily fit into crowded electrical panels or around busbars
  • Current sensing range from 2.5A to 50,000A for compatibility across any system.
  • Field-configurable CT ratios: 500A, 1kA, 2.5kA, 5kA, 10kA, 25kA, 50kA
  • Individual CT ratios can be configured for each channel. Works in any single phase application with different current ratings.
  • Compatible with both 50Hz and 60Hz systems

RIK 333mV Series Overview

What is an 333mV Integrator?

Integrators can amplify and transduce the standard output from the Rogowski coil to a commonly accepted signal, such 333mV. The integrator can also compensate for the Rogowski coil's inherent 90 degree phase shift. The 333mV output signal is a commonly used to monitor energy usage from a faciliity’s panel or through individual load circuits. It provides an easy-to-use solution for 3rd party power meters or other equipment..
