can anyone gimme circuit using current x'former so that i can see the current waveform using CRO... it should shift wrt to voltage waveform when the phase angle of the supply is varied

 

Hello,

Your question is very cryptic.
Here is a link to pages with various types of transformers including current-transformers.

well this is what i want...
current x'sformer should be connected to source in such a way that by varying the phase angle of source the o/p waveform phase should change accordingly.....
i.e i want to see the current eq waveform on cro...
or any circuit which will show me the current eq waveform on cro i.e when phase shift is given to the source i should see the waveform shift on the cro wrt to the voltage waveform of the source...

 

Hello,

Do you mean an oscilloscope with CRO?
What is WRT?

WRT means with respect to..
and yes... by cro i meant oscilloscope

 

Hello,

Here are 3 PDF's with information on current transformers.

sorry but that didn't help...
the whole thing was about detecting phase angle between the voltage and current...
tried using current former but didn't work...
i'm desperatly seeking circuit that can give me phase angle between supply voltage and current.. the following type of circuits will do
1) circuit which wil give me current and voltage waveform at the output ............ the should change in phase when power supply phase angle is varied
2)circuit that will generate voltage signal proportional to the phase angle between current and voltage

 

Hello,

You are trying to measure AC voltages?
Here is a link to AC measurements including phase measurement with an oscilloscoop.

The link comes from this page: http://www.educypedia.be/electronics/measurement.htm

well plz suggest a circuit where, wen it's output connected to cro will show me current waveform... that was whole purpose of the current transformer....
changing the phase angle of the supply should change the phase of the voltage waveform with respect to the current one

 

Do you have an Oscope?

You ought to read this section of the AAC eBook, with special emphasis on this chapter.

 

well let me get it like this
u can't observe current waveform on CRO...
please gimme circuit to separate the voltage and current waveforms so that when i change the phase of power supply there's phase change in the current and voltage waveforms of that suppl observed on CRO..

 

I have had good luck with this current probe. John

 

Hello,

Another possibility is the use of Halleffect sensors.
