Product Overview

The clamp on flexible Rogowski coil current transformer is an AC current transducer. It combines the benefits of a thin, flexible, clip around Rogowski sense coil with a signal conditioner providing accurate true rms measurement of voltage or current.

The catalogue covers flexible core coils FRC with BNC and G1 Rogowski integrator giving mV or 333 mV output, flexible rope CT FRC with G2 integrator for four current range measurements, and the FRC-420 with an input of 1 to 10 kA and a BNC AC current probe output.

FAQ

Questions Buyers Ask

What is the difference between the G1 and G2 integrator?

G1 gives a single fixed output such as mV or 333 mV. G2 offers four switchable current ranges from one coil, which is useful on a test bench where the load varies widely.

Why a BNC connector?

So the coil plugs straight into an oscilloscope, power analyser or data acquisition front end without an adaptor.

Can it measure a transient?

The 10 Hz to 10 MHz frequency range and 2 Hz to 100 kHz bandwidth make it suitable for transient and harmonic work as well as fundamental measurement.
