Feature
  NRC is a flexible current transducer based on Rogowski principle, particularly suitable for measurement in combination with portable devices. NRC coils 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 transducers 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.
  NRC 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 kA. The  Rogowski coils must be connected to an electronic integrator for 90° phase shift compensation and frequency equalization. Our DIN-RAIL and panel meters can interface  Rogowski coils directly 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 with the extremely flexible input programming of our portable meters, allow to carry out measurement by all applications.


What is a Rogowski coil?
    Rogowski coils have been used for the detection and measurement of electric currents for decades.The are based on a simple principle :an "air-cored"coil is placed around the conductor in a toroidal fashion and the manetic field produced by the current induces a voltage in the coil.The voltage out put is proportional to the rate of change of current .This voltage is integrated,thus producing an 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 infiuenced 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 coil and conditioning electronics.Rogowski coil current measuring system consists of a combination of a combinaion of coil and conditioning electronics.Rogowski coil current transducers are used for the AC measurement 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 can be easily manufactured according 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.

Safety and warning notes
In order to guarantee safe operation of the transducer and to be able to make proper use of all features and functions, please read these instructions thoroughly! Safe operation can only be guaranteed if the transducer is used for the purpose, it has been designed for and within the limits of the technical specifications. 
Caution! Risk of danger
Ignoring the warnings can lead to serious injury and/or cause damage!
The electric measuring transducer may only be installed and put into operation by qualified personnel that have received an appropriate training, The corresponding national regulations shall be observed during installation and operation of the transducer and any electrical conductor. The transducer shall be used in electric/electronic equipment the respect to applicable standards and safety requirements and in accordance with all the related systems and components manufacturers' operating instructions.
Caution! Risk of electrical shock
When operating the transducer, certain parts of the module may carry hazardous live voltage (e.g., Primary conductor). The user shall ensure to take all measures necessary to protect against electrical shock. The transducer is a build-in device containing conducting parts that shall not be accessible after installation. A protective enclosure or additional insulation barrier may be necessary. Installation and maintenance shall be done with the main power supply disconnected except if there are no hazardous live parts in or in close proximity to the system and if the applicable national regulations are fully observed.
Safe and trouble-free operation of this transducer can only be guaranteed if transport, storage and installation are carried out correctly and operation and maintenance are carried out with care.
Caution! Risk of electrical shock
Do not apply around or remove from uninsulated hazardous live conductors which may result in electric shock, electric burn or arc flash.
WARING!
Do not stress the coil by applying any kind of mechanical force (transport, storage pressure, tight bending.) which will dramatically degrade the device's accuracy.Free Installation of Sensors Flexible Rogowski Coil Reliable Rogowski Coil
