Finally I got the results that I wanted.
I completed the circuit using a simple trasformer as in the beginning but paying attention on the connection.
I put a tension divider after the potential transformer and a burden resistor as you all advised me.
After all the advices I finally finished...
Sorry I didn't notice that I forgot to put a burden resistor.
I'm having trouble to model the current controlled current source because I have two CT's here that I want to model to multisim.
One is 30A/1V and the second one is 100A/50mA. The second one has a relation of 1:2000 and a burder...
I have done it as two circuits, one more simple, just with an oscilloscope and a current clamp to see the phase between voltage and currend and gives me the result that is attached.
The Second one is a new zero crossing circuit. I changed the Op Amp to the LM 358 Dual Comparator and eliminated...
Okay, I'll do a simple schematic just to meansure the voltage and the zero crossing at the voltage and post the results, after it I'll start to do the current meansure
Ok. I'll do it and post the results.
I'm going to see if I can find a current transformer on multisim because the only thing that I found was a Current Controller Source but I guess that is not the transformer.
I need to simulate a non invasive current transformer because in a factory we cannot...
Dear all,
I'm trying to do a power factor measurement for academic work. I'm using the zero crossing detection on the voltage and the current so that I can do the difference between then and convert to angle.
Using the Op-Amp 741 as a voltage comparator I'm not able to get the phase wave of...
