RC-MINI-6-36 is a MINI flexible current transducer based on Rogowski principle.

- 6 (coil section in mm)
- 36 (window size in mm)

They can be used in all those applications, in which traditional transducers are not fitting
due to its size and/or weight.

Due to its specific features, flexible Rogowski coil is an extremely confortable solution for current
measurement and can be used in a number of cases where traditional current transducer is not
the adequate solution.

RC-MINI-6-36 coil is provided with a shield against the influence of external magnetic fields,
therefore it grants a stable measurement from low currents to hundreds of A.

The Rogowski coils must be connected to an electronic integrator for 90°
phase shift compensation and frequency equalization.

Available only in Orange.

What is a Rogowski coil?

Rogowski coils have been used for the detection and measurement of electric currents for decades. They are based on a simple principle: an “air-cored” coil is placed around the conductor in a toroidal fashion, the magnetic field produced by the current induces a voltage in the coil. The voltage output is proportional to the rate of change of current.

This voltage is integrated, thus producing an output proportional to the current.

By using precision winding techniques, especially developed for the purpose, the coils are manufactured so that their output is not influenced by the position of the conductor within the toroid, and to reject interference from external magnetic fields caused, for example, from nearby conductors.

Basically, a Rogowski coil current measuring system consists of a combination of a coil and conditioning electronics. Rogowski coil current transducers are used for the AC measurement.

Use and choice of the right current transformer

The choice depends on the type of application you have to face, a machine rather than a retrofit on an existing switchboard, or the need for a solution that can work well even without having made an inspection.

Master Chips has in stock various models of Current Transformers to be combined with your network analyzers or to be connected to those managed by us.

Often, in the measurement of electricity consumption, the choice of the current transformer is underestimated. This can cause inconvenience during installation by the operator, up to the introduction of measurement errors that can affect the energy measurement of our energy meter.
