Brief Introduction of Rogowski Coils, from Three Aspects
Jun 17 , 2022
What is the Rogowski coil? The Rogowski coil is a flexible clip-on hybrid inductor coil that can be easily coiled around a current conductor for measuring. It is capable of measuring large currents of several thousand amperes without expanding the size of the voltage transformer. Rogowski coils are electronic voltage transformers used to measure alternating currents such as fast transients, single...
