Rogowski Coil Flexible Current Transformers

AcuCT Flex Series

High specification line of flexible current transformers that measures AC current for power metering, power quality analysis and general use. The Rogowski coil provides a versatile solution when space is limited and requires a rope-style CT to physically wrap around a irregular shaped conductor or wire.
  • High accuracy for demanding applications
  • Wide frequency range means excellent choice for harmonics and power quality
  • Wide current input range from 5A – 50,000A AC
  • Choice of 16″, 24″, 36″ or 47″ length
  • No additional power supply needed when used with Acuvim II Series meters
  • Fully customizable selection of flexible CT

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.
