RIK-1AR:ATR-04

Current Sensors Overview

The Accuenergy RIK-1AR:ATR-04 is a relay-class Rogowski integrator kit designed for protection relays and meters accepting a 1A nominal CT input. It pairs with flexible Rogowski coils to provide selectable primary current ratings of 50A, 200A, 500A, 2000A, or 5000A. The system delivers a standardized 1A output signal suitable for industrial protection applications. It requires an external 24Vdc power supply, typically the Accuenergy PSU-240-24, which accepts 100-240Vac input. This configuration ensures compatibility with standard protective relay devices requiring precise current integration.

Current Sensors Feature Summary

• Relay-class performance meeting IEC 5P20 protection standards
• Plug-and-play installation with flexible Rogowski coil pairing
• Selectable primary current ratings from 50A to 5000A
• Standardized 1A nominal output for protection relays

Current Sensors Applications

• Protection relay current sensing
• Industrial metering devices with 1A input
• Electrical protection systems requiring high accuracy

Current Sensors Procurement Notes

Verify that the specific order includes both the RIK-1AR integrator unit and the compatible ATR-04 Rogowski coil assembly. Confirm the required selectable primary current rating (50A, 200A, 500A, 2000A, or 5000A) matches the application needs. Ensure the necessary 24Vdc power supply, such as the PSU-240-24, is procured separately if not included in the kit. Check that the receiving equipment supports a 1A nominal input signal.

Current Sensors Selection Notes

Select this model when integrating Rogowski coils with protection relays or meters that require a 1A nominal input signal. Choose based on the specific primary current range needed, available in options from 50A up to 5000A. This integrator is suitable for applications demanding IEC 5P20 protection class accuracy. It is not intended for general metering classes requiring different output signals or accuracy levels.

Current Sensors Part Context

The RIK-1AR belongs to Accuenergy's RIK series of Rogowski integrators, specifically engineered for protection class applications. Unlike general-purpose integrators, this variant focuses on compatibility with protective relay devices. The :ATR-04 suffix denotes the specific coil configuration paired with the integrator. This series provides a modular solution for modernizing electrical protection systems using flexible current sensing technology.

Current Sensors Replacement Considerations

Direct substitutes include other models within the Accuenergy RIK series, such as the RIK-5A for 5A output requirements or variants like RIK-V-3 and RIK-mA-3 for different output types. Ensure any replacement maintains the 1A nominal output specification and IEC 5P20 protection class if used with existing protection relays.
