Rogowski Coil measures Ac current with maximum accuracy. This article, however, covers the fresh knowledge of Rogowski coils and their applications. Because these coils never stop evolving. What it was five years ago is not the same as what is now.
Key Takeaway
Rogowski coil design involves careful consideration of materials, construction techniques, and integration methods. You must optimize. It is key to reach the accuracy and performance you want in your measurements.
History of the Rogowski Coil
Rogowski coil was first invented by Walter Rogowski. He was a German Physicist in the 20th century.
Rogowski's innovation was an innovative work on electromagnetic theory and measurement techniques. The design he made consists of a helical coil wound on a non-magnetic core. It revolves around the process of measuring AC currents.
Rogowski's design went through many changes in the past. Now we use these coils in modern materials, power quality analysis, clamp meters, and many more.
