333mV Rogowski Coil Integrator Kit – RIK 333mV Series








333mV Flexible
Current Transformers
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

How it Works
If your third-party device does not include integrator circuitry, or you require a specific industrial output signal, select an Accuenergy RIK with an output option compatible with your device.
AcuCT Flex Rogowski Coils
The AcuCT Flex Rogowski coils are available in multiple lengths and flexible, rope-like form factor is ideal for measurement around irregularly shaped conductors or in crowded electrical panels. With a wide measurement range, Rogowski coils are the superior choice for demanding applications.

Accuenergy Rogowski Integrator Kits (RIK)
The Accuenergy Rogowski Integrator Kits (RIK) are designed to bridge the gap between AcuCT Flex Rogowski coils and devices without built-in integrator circuitry. Select from a number of industry-standard output signals and adapt to any installation with multiple, field-configurable ratio options.

Third-Party Devices without an Integrator
Add the convenience of AcuCT Flex Rogowski coils to any third-party device without a built-in integrator. The Accuenergy Rogowski Integrator Kit connects devices such as such as a power meters, PLCs, RTUs, IEDs, or controllers to versatile Rogowski coils to overcome a range of installation challenges.

EMS Platforms, Gateways, or Servers
An effective energy management system, comprised of gateways, servers, and other hardware, relies on high-quality, reliable energy data provided by power meters and high-accuracy sensors, such as the AcuCT Flex Rogowski coils, for comprehensive energy management.
