FRC is a flexible current transducer based on Rogowski principle, particularly suitable for measurement in combination with portable devices. NRC coils are available in different sizes and can be supplied according to customer’s design, therefore they can be used in all those applications, in which traditional transducers are not fitting due to its size and/or weight.
• High linearity from 1A to 100kA
• Wide dynamic range
• Very useful with large size or awkward shaped conductors or in places with limited access
• No danger from open-circuited secondary
• Not damaged by large overloads
• Non-intrusive, no power drawn from the main
• Measurement uniformity at any position of the conductor inside the coil
• Excellent degree of rejection to the external current conductor
• Frequency: 50/60 Hz nominal, (safe to operate at any frequency)
