arranjo de medição para a detecção de correntes alternadas

摘要

The invention relates to a measurement arrangement for connection to an energy and power meter and for connection to a Rogowski coil for detecting of alternating currents of a conductor being metered. The measurement arrangement has an integrator circuit to create a voltage signal proportional to the detected alternating current and a voltage/current converter to create an output current that is proportional to the voltage signal created by the integrator circuit. Furthermore, the invention relates to a measurement system that has an above-described measurement arrangement and a Rogowski coil for detecting of alternating currents of a conductor being metered.
