A Guide To Designing Your Own Rogowski Sensor (Part 2)
by Gregory Mirsky, Design Engineer, Deer Park, Ill., How2Power Today, May 15 2024
Focus:
In part 1 we learned that a response to the trapezoidal current of a Rogowski coil is
essentially a derivative of the measured current waveform. To restore the current
waveform, we have to integrate the coil’s output voltage. In this second part of the
article, the author derives the integrator’s transfer function and shows how this is used
to select the integrator’s key components.
What you’ll learn:
- How to design a low-cost Rogowski coil current sensor
- How to design the integrator for a Rogowski coil current sensor
