The RIK 1AR is a protection relay class Rogowski Integrator. 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.

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.

Compatible Accessories (Each sold separately):
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.
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.
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.
Where most protection relay applications rely on heavy, rigid current sensors, the RIK-1AR allows this equipment to take advantage of flexible, lightweight Rogowski coils.
