About Current Sense Transformers

current-sensing-transformersCurrent sensors serve one specific purpose -- to detect alternating current (AC) or direct current (DC) in a wire in order to generate a proportional signal. Current sensing is especially critical for power metering applications. The technology behind current sensors (more specifically current sense transformers) comes in various forms:

  • Low resistance current shunts
  • Current transformers with amorphous metal core
  • Hall Effect devices
  • Rogowski Coils (such as what's found in our Sidewinder products)

Each type of current sense transformer comes with their own unique set of strengths and weakness, which are important to understand before selecting them for your application. Compare them side-by-side and discover more about the benefits of the Rogowski Coil by downloading our white paper here.
