Hejsan!
My friend has an very old high voltage/power pulse generator he bought at auction long time ago, and now we want to measure the output in terms of power/energy.
We made a 100:1 high voltage probe to measure the output voltage, it's basically just a restive voltage divider. And then we made a Rogowski coil and calculated the mutual inductance M using formula (7) in this paper http://www.imeko.org/publications/tc4-2008/IMEKO-TC4-2008-148.pdf with the following values:
μ0 = 1.25663706143592E-05
a = 0.017 Meter
b = 0.024 Meter
N = 120 Turns
The calculated M is 4.5388E-07 H which gives a scaling factor of 1/M =
2203213 for the Rogowski coil output.
And this is the output both measured and calculated, the green trace is the integral of the Rogowski coil output multiplied by the scaling factor.
