phasor values

[muscles05]

Hello so i am trying to get a few phasor values from a output voltage of a simple voltage divider that i made. I the voltage divider connect to a mydaq, i am basically treating my mydaq like a pmu (phasor measurment unit) so i can estimate the phasor from the output voltage. I have everything set up as far a program in labview i get the waveform and value but dont know how to get phasor values from this voltage reading.

How would you get phasor information if you were measuring the waveform with an oscilloscope?  You need to have a timing reference.  You need to synchronize the voltage waveform measurement with that timing reference.

How you do that depends on what you choose for the reference.

I not measuring with a oscilloscope, i have a voltage divider set up and the output voltage is 2.83, i have a labview code that displays that voltage but since its DC i dont think i could get phasor correct. What do you mean by time reference.

Hi muscles05,

Unfortunately, phasor analysis is not possible with a DC signal. Please see the link below for more information about phasors.

what type of a expierment can i run where i can sample a voltage get phasors out of it.

Here are some phasor domain examples: http://www.calvin.edu/~svleest/circuitExamples/PhasorDomain/

You can use NI products to simulate or measure these example circuits and confirm that you are coming to the correct solution.
