Ø6 Flexible Rogowski Coil Fixed by Cable Ties

  • High linearity from 1A to 100kA/500kA
  • 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

The ESCT-RC Series flexible current transducer has been designed for accurate non-intrusive measurement of alternating current (AC), high-speed current pulses or distorted waveforms where traditional rigid core CTs are unsuitable.

ESCT-RC Series coils can be customized in different sizes. The ESCT-RC Series window size is as small as 16 mm, coil section only 6mm, which is the smallest Rogowski coil in the world for electric power applications. The ESCT-RC Series can also be fixed to the conductor by cable ties. Therefore, flexible Rogowski coil is an extremely comfortable solution for current measurement and can be used in all applications where traditional CTs are not suitable due to their size and/or weight.  

The Rogowski coil does not require power supply, but must be connected to the integrator to achieve 90° phase-shift compensation and frequency equalization.  

We also provide Rogowski coil related integrator and meter solutions. Our meter can be connected directly to the Rogowski coil without the need for an external integrator. This is an advantage because there is no external box or any power supply, so it is easy to use.
