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..

Rogowski Coil Benefits

Rogowski Coil current transformers are designed for precision AC current measurement in power metering or general energy monitoring applications. Flexible Rogowski coils provide a versatile solution in crowded electrical panels where rigid-body current transformers simply will not fit. Much like a split core current transformer, the user-friendly locking connector opens for easy integration into existing panels without disconnecting wires. Available in four sizes to suit any application.

Included in Kit

Each Rogowski Integrator Kit includes:

  • A three channel integrator
  • Three AcuCT Flex current sensors in one of four available sizes
  • 100-240Vac DIN-rail mount power supply
