Accurate current measurement is crucial in electrical engineering. At Smilics Technologies, we've been perfecting our sensor solutions to the highest quality standards since manufacturing our first split-core current transformer in 1994 and our first Rogowski Coils over 15 years ago.
Do you know the differences between these two solutions?
Two popular devices used for this purpose are Current Transformers (CTs) and Rogowski Coils. This article aims to highlight the differences, advantages, and disadvantages of these two devices.
CTs operate on the principle of magnetic induction, translating high-current signals into lower, safe levels suitable for metering devices or protective relay equipment.
Advantages of CTs
Disadvantages of CTs
Named after Walter Rogowski, these coils are used for the measurement of alternating current (AC) or high-speed current pulses.

Disadvantages of Rogowski Coils
In conclusion, both CTs and Rogowski coils have their unique advantages and disadvantages. The choice between the two depends on the specific requirements of the application. While CTs are more suitable for applications requiring high accuracy, Rogowski coils are more suited for applications requiring flexibility and a wide measurement range.
Whatever solution best suits your needs, at Smilics Technologies we have standard and customised solutions for whatever your needs may be.
