Rogowski Coil Features
The AcuCT 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.
Wide Current Sensing
Measure current from 5A to 50,000A on each standard coil. Higher current range available upon request.
Wide Frequency Response Range
Standard frequency response range of 10Hz- 20KHz. Higher frequency response range such as Mega Hz available upon request.
High Accuracy & Linearity
0.5% accuracy across the entire range of measurements.
4 Standard Length Selection
We offer four lengths of coil, 16″, 24″, 36″ and 47″. Custom lengths available upon request.
