5A Rogowski Integrator Kit

  5A Rogowski Integrator Kit (RIK) brings the convenience and flexibility of Rogowski coil current transformers to any device that accepts a 5A input, such as a power meter. The Rogowski Integrator Kit delivers a simple, plug-and-play solution to situations where physical space may be limited, such as crowded electrical panels, or to installations that include large, irregularly shaped conductors like busbars. Highly adaptable, the seven user-selectable input ranges ensure the Rogowski Integrator Kit will be compatible with any system up to 50,000A AC. Each kit also includes three, flexible Rogowski coils in one of four standard lengths.




l  Flexible rope-like current sensor, designed to easily fit into panels where space may belimited

l  0-5A rated output that works with any power meter with 5A nominal current transformer input

l  Current sensing range from 2.5A to 50,000A to fit all systems

l  Field-configurable CT ratios: 500A, 1kA, 2.5kA, 5kA, 10kA, 25kA, 50kA

l  Individual CT ratios can be configured for each channel.

Integrators can amplify and transduce the standard output from the Rogowski coil to a commonly accepted signal, such 5A. The integrator can also compensate for the Rogowski coil's inherent 90 degree phase shift. The 5A output signal is a commonly used to monitor energy usage from a facility’s panel or through individual load circuits. It provides an easy-to-use solution for 3rd party power meters or other equipment.

Function and Application 

Function General measurement and protection in power systems for highly mobile or space-constrained or uninterrupted power systems.

Application Uses: power instrumentation, electronic multi-function energy meter and field calibrator, instrumentation measurement and protection.

Installation instruction:


When flexible rogowski coil  measurement probe connected, the cable under test should be placed in the middle of the flexible rogowski coil and the coil can be kept vertical to effectively reduce the measurement error.

in daily use , please ensure the correct connection of the XS1 terminal positive and negative polarity of the power supply, once incorrect connection, the inside chip will be damaged.

If the output channel for more than 5 amps RMS may cause RōCoilTCA-5 to overheat and damage.
