The Algodue MFC150/F series of flexible Rogowski coils have been developed with a built-in integrator providing a 333mV full-scale output. This makes the MFC150/F compatible with any power metering devices capable of receiving a 333mV CT input.

The MFC150/F is available in 11, 17.5, and 27cm coil diameters, with full-scale values of 1kA, 2kA, and 5kA respectively.

These Rogowkis coils are perfect for use in applications where traditional solid-core and split-core CTs are not suitable or cost effective, due to space limitations, conductor size, or multiple conductors requiring measurement.

Rogowski coils can be used in similar circumstances to current transformers but for many applications they have considerable advantages:

  • Wide dynamic range. The same coil can be used to measure currents from mA to several kA, it is enough to change the RC value in the integrator.
  • High linearity. According to the manufacturing (size, inductance value, …) the maximum measurable frequency can range up to hundreds of kHz and in some special models also MHz.
  • Very useful with large size or awkward shaped conductors or in places with limited access. Thanks to the structure without hard core, the coil can be easily manufactured according to the application or to the available space.
  • Unlike traditional current transducers, there is no danger from open-circuited secondary terminals.
  • They cannot be damaged by large overloads.
  • They are non-intrusive. They draw no power from the main circuit carrying the current to be measured.
  • They are also light weighted and in some applications are light enough to be suspended on the conductor being measured.

The transducer does not measure direct currents but, unlike a current transformer, it can carry out accurate measurements of AC component even if there is a large superimposed DC component, since there is no iron core causing saturation. This feature is particularly useful for measuring ripple currents for example in battery charging systems.
