Can't find a wattmeter(380V/5A) to do a "Balanced three-phase" experiment

Can't find a wattmeter(380V/5A) to do a "Balanced three-phase,three-wire, delta connected system" experiment.

I've search the component database but cannot find anything, do I look at the wrong place???

Hi Riaan,

Can you please explain more about the component you are looking for.

Thank you,

Hi Leila F,

I need to connect 2 wattmeters in a circuit that is a Balanced three-phased, three-wire, delta connected system.

In all three impedance there is a resister = 100 ohm, and a capacitor = 36 uF with the following voltages: Vby = 380[0degrees V

Vrb = 380[-120degrees V

Vyr = 380[120degrees V

Riaan,

 I don't think you would have problem using a regular wattmeter of the Multisim.For 3phase power measurement you can put two watmeters and then add the results of the two.You can also send your circuit if you still have problem.
