Exercise on a three-phase system where to evaluate the indication of the wattmeter

[pizzico85]

Hi all, I am new to this forum and I hope you can help me.

I have the following three-phase system where I have to evaluate the indication of the wattmeter W. Available data is: V = 380 V, R = 12 Ohm, R' = 120 Ohm.

Can you make me understand the process for obtaining W?

do you know how to convert var to Watts using the power triangle?
