ATP40 Three phase Din rail 40mA integrator
 ATP40 is a Three phase DIN-RAIL 40mA output Rogowski coil integrator which adopting standard 35mm din rail installation.
What does Integrator do?
• Rogowski coil output is weak voltage mV signal, ATP40 has ability to amplify and convert it to standard signal which could match with the signal required by electricity meters.
• Rogowski coil output is proportional to the frequency of the measured current, the signal equalization ensures a linear response on a wide frequency range. ATP40 allows to use coils on different electrical network frequencies, keeping the same output level over the frequencies.
• An integrator is essential to equalize and shift by 90° the output signal from the Rogowski coils. It consists of an active electronic circuit with negligible offset and a good linearity.
Feature
ATP40 can be combined with any model and size of Y-FCT, MRC,VRC or NRC Rogowski coils.
The available output value : 0-40mA AC
The input value can be customized according to the application.
ATP40 and Rogowski coil is a very flexible system, the combination as a current sensor is used to measure AC current. The output 40mA AC current signal can be directly access to the electricity meter terminal. The sampling resistance can reach up to 20 ohms. Due to its specific features, flexible Rogowski coil is an extremely suitable solution for current measurement and can be used in a number of cases where traditional current transducer is not the adequate solution.


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 and 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.

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.
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.
