3P Rogowski Coil CT

The Flexible Rogowski coil current transformer series is designed for easy-integration in a variety of applications and systems. Rope Style Form Factor Rope-like coil allows it to fit into any constrained spatial configuration ranging from panels, wire bundles or irregular sized bus where regular solid core CT or split core CT cannot be used.


The split design permits non-contact AC current or current pulse measurement without requiring that the primary conductor be taken offline and disconnected for the current sensor installation. This method provides for the safe, easy and portable measurement of current. 
A current sensor that is based upon the Rogowski Coil principle offers significant advantages over the standard magnetic core current transformer products. Specifically, since the sensor does not incorporate a magnetic core, magnetic core saturation (the point where incremental increases in magnetic flux are not reflected in proportional increases in secondary signal outputs) is avoided
