PROTECTIVE RELAY
ROGOWSKI COIL INTEGRATOR

The RIK 1AR is a protection relay class Rogowski Integrator Kit. This plug-and-play solution is designed to streamline the installation and configuration process between the sensor and protection relay, power meter, or other device with a 1A nominal input. It pairs with a Rogowski coil to easily install in places where spatial constraints or conductor size prohibit the use of rigid-body current transformers.

  • Easy-to-install, plug-and-play integrator used with any protection relay, energy meter, or device with a 1A nominal current input
  • Protection Class: 5P20 (IEC 61869-2)
  • Wide current sensing range from 0.25A to 100,000A for compatibility across any system
  • Field-configurable CT ratios: 50A, 200A, 500A, 2000A, and 5000A
  • Compatible with both 50Hz and 60Hz frequency systems
  • Paired with a single rope-style Rogowski current sensor to easily fit tight spaces with 95% less weight than a traditional relay class CT (sold separately)

RIK 1AR Overview

What is a Protection Relay?

A protection relay is an intelligent device found in electric power systems that is responsible for safeguarding sensitive electrical equipment such as motors, transformers, transmission lines, or generators from abnormal power conditions. They receive input from instrument transformers, such as flexible Rogowski current sensors connected via an integrator, and compare the incoming values to a set value (trip value) to detect when a fault has occurred. In response, a circuit breaker is tripped to isolate the fault from the rest of the system and prevent damage.

Rogowski Integrator Benefits
  • Allows protection relay devices which are normally incompatible with Rogowski coils to take advantage of the flexible, user-friendly installation
  • Save money: A Rogowski sensor paired with a RIK-1AR integrator is less expensive than a protective relay class sensor and can be used with existing equipment
  • Offers a wide current sensing range with field-configurable ratios for broad compatibility across systems & devices
Included in Kit

Each RIK 1AR kit includes:

  • A single channel integrator
  • 100-240Vac DIN-rail mount power supply
RIK 5A - Overview

RIK 1AR Main Features

RIK 1AR - Worldwide Compliance.

WORLDWIDE COMPLIANCE

The RIK-1AR is suitable for use in a range of applications where protection relays are commonly found, including critical infrastructure such as power substations, utilities, commercial & industrial facilities. Robust by design, it has been tested to meet strict, worldwide compliance standards.

Key Specifications:

  • Protection Class: 5P20 (IEC 61869-2)
  • UL Listed & CE Mark
  • Enclosure meets UL 94V-0 requirements
  • Compatible with 60Hz and 50Hz systems
RIK 1AR - Field Configurable CT Ratio.

FIELD CONFIGURABLE CT RATIOS

Designed for use with a wide variety of systems, its easy to switch the RIK-1AR between low and high amperage loads with a choice of five field-configurable CT ratios.

Key Specifications:

  • Adjust between 50A, 200A, 500A, 2000A, and 5000A at the flip of a switch
  • Integrator can measure current from 0.5% to 2000% of rated current
  • Industry-leading sensing range: Use on loads up to 100kA
RIK 1AR - Broad Compatibility.

BROAD COMPATIBILITY

The RIK-1AR is device agnostic and is designed for a direct connection with any protection relay, power meter, or other measurement device with a 1A nominal current input.

Key Specifications:
