We would like to expand the frequency range to 50Hz - 100kHz
But based on following figure
I am not quite sure this will be possible with the vitroperm core.
ah ok, thank you.
If we increase the windings of the secondary to increase the voltage at its terminals, what are the consequences?
I've read that the higher cut off frequency will go down because of the leakage inductance and stray capacitance.
But is there any formula to estimate the higher...
if we use a tape wound core the lower cut off frequency will easily be under 50 Hz.
But what about the sensitivity = R(shunt)/N(windings) ?
if we use an active I/V converter, then R = 0 (ideally) so the sensitivity will be also 0?
after the current transformer we want to filter the signal (to...
Indeed, my apologies, the higher currents are for the 27 MHz design
In the 50 Hz design, i need to able to measure mA's
And I am a student in electronical engineering, but I am fairly new to the design of transformers.
I can calculate the inductance of the secundary coil ( L = A_l * N^2 ), but...
Hi,
I want to make a toroid current transformer with a large aperture so that it can fit around the arm or ankle.
The current transformer is meant to measure the induced current in the body ( arm or ankle ) caused by electromagnetic fields.
I found some ferrite toroid cores on ferroxcube.com...
