Hi,
For one of my projects i've to measure a signal from a rogowskicoil.
But the output signal of the coil is not integrated.
I've found the integrationfunction at the mathchannels but i can't obtain the result i expect
The formula should be: i(t) = (c) * integral(A(t) * dt) with c = contant (this case 36153),
i(t) = current (Amp),
A = signalvalue (mV)
The closed i can do is: c *integral((A(T))*derivative(T))
But without a result
Does anyone knows a solution?
Thanks!
Dries

Re: integration (rogowski) of a waveworm
The voltage produced by a Rogowski coil is
V = c x (dI/dt)
where c = Is the constant of the coils properties
See  https://en.wikipedia.org/wiki/Rogowski_coil
So current I in the cable is
I = integral(V/c)
V = c x (dI/dt)
where c = Is the constant of the coils properties
See  https://en.wikipedia.org/wiki/Rogowski_coil
So current I in the cable is
I = integral(V/c)
