feature
MRC is a mini flexible current transducer based on Rogowski principle,particularly suitable for measurement in combination with devices.MRCcoils are available in different sizes and can be supplied according to customer's design,therefore they can be used in all those applications,in which traditional trabsducers are not fitting due to its size and/or weight
Due to its specific features,flexible Rogowski coil is an extremely comfortable solution for current measurement and can be used in a number of cases where traditional current transducer is not the adequate solution
MRC coil provided with a shield against the influence of external magnetic fields;therefore,it grant a stable measurement from low currents to hundreds of kA.The Rogowskicoils must be connected to an electronic integrator for
90° phase shift compensation and frequency equalization .Our meters can interface Rogowski coils combined with the extremely integrators.This is an advantage because there are no external boxes or any power supply with consequent ease of use.The particular without the need of the external integrators.This is an advantage because there are no external boxes or any power supply with consequent ease of use.The particular features of the Rogowski coils combined whit the extremely flexible input programming of our portable meters,allow to carry out measurement by all applications.
WHAT IS A ROGOWKI COIL?
Rogowski coils have been used for the detectionand measurement of electric cuurents for decades.They are based on a simple principle:an"air-cored"coil is placed around the conductor in a toroidal fashion and the magnetic field produced by the current induces a voltage in the coil.The voltage output isproportional 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 their output is not infiuenced by the position of the conductoe whithin the toroid,and to reject integrated, from external magnetic fields caused,for exanple,from nearby conductors.Basically,a Rogowski coil current measuring system consists of a combination of coil and conditioning electronic.Rogowski coil current transducers are used for the ACmeasurement.
They can be used in similar circumstances to current transformers but for many applications they have considerable advantages:
Wide dynamic range
High linearity
Very useful with large size or awkward shaped conductors or in places with limited access.Thanks to the structure without hard core,the coil be easily manufacturedaccording to the application or to the available space.
Unlike traditional current transducers, there is no danger from open-circuited secondaries.
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.
