Topic: Shift of phases between a current and pressure

Prompt, how it is possible to calculate a subject, at known active and reactive capacity? If to take  from power factor not clearly what and roots to take? If it is not enough data, what data help to select the correct root?

To me it is curious, for what it was required to search ? And whence  both capacities? PS I  forgot partially and  seriously I will help. But the subject is interesting.

But the subject is interesting. Yes there is no singular problem. Simply from the clever counter the instant capacities, currents, pressure, corners between phase pressure are read, power factors etc. Simply the program should deduce the vectorial chart of currents and pressure.

Why then phase shift not to consider from power factor? Well I just about it wrote, and  two roots, with different signs.

Or absolute value? Yes I basically understood already as, under your help. The corner basically can be received as atan (Q/P), but in the presence of power factor from the counter, value acos (fi) signed products P*Q undertakes.

The corner basically can be received as atan (Q/P), but in the presence of power factor from the counter, value acos (fi) signed products P*Q undertakes. I.e. the sign is? Then at me all converged. Well, and a question in : what values cos (fi) turn out in practice?
