Hi,
I'm trying to plot in a phasor rapresentation current data acquired from CTs in a real 3p circuit.
I have access to the data in a txt file, currently I'm just plotting the three sinusoidal components in time domain, but I'd like to have a phasor representation to see theirphase shift.
Is there an easy why to do it? I've tried compass but it gives weird results. Thanks.
Marco

Please attach the text file (or a representative sample from it), explain what it contains, and what you want from it.
It would also help if you explain what ‘CTs in a real 3p circuit’ means. I have not previously encountered of those terms, at least not together as you used them.

Hi,
sorry for not being clear.
CTs in a real 3p circuit’ means current transformers in a real three phase circuit.
A part of the code is:
i1= current(:,1);
i2= current(:,2);
i3= current(:,3);
t1= length (i1);
t=[0:0,1:t1-1];
figure
plot(t,i1,t,i2,t,i3)
What I'd like to do is plotting the 3 currents in a phasor rapresentation, to see the phase shift between each signals. Thanks.
