Residual Magnetism on Current Transformers


Live Virtual Webinar

March 23, 2023

13:00 – 14:00 AEST


We are hosting monthly webinars on technical topics this year!

As an attendee, you will be entitled to a one-month FREE RemAlyzer CTA license.

Join us for this one hour presentation and Q&A and learn about the impact of a CT magnitise core behaviour.

Residual magnetism may occur as a consequence of high fault currents containing transient components, direct currents applied to the current transformer during winding resistance tests or during a polarity (wiring) check. Depending on the level of remaining flux density, residual magnetism can dramatically influence the functionality of a current transformer by driving it into early saturation.

In this webinar we will explore some reasons on why to consider this additional point when testing your current transformer.

What you will gain:

  • Introduction into Current Transformer
  • Different CT testing methods and standards
  • Advantages of MBT and Demagnetization of CTs including Remanence
