dephasage ou
facteur de puiss: cosPhi=p/s

puiss active: P=u*i*cosPhi

puiss reactiv: Q=u*i*sinPhi
               Q=P*tanPhi

puiss apparen: s=u*i
               s=sqrt(P**2+Q**2)

intensite eff: i=S/U

 Phi=Q/P

rendement: Putil/Pactiv
i=P/u*cosPhi

u en volts
i, I en amperes
P en watts
Q en VAR
S en VA
Phi=cosPhi dans tanPhi
pq relever le facteur de puiss
I=Ptot/u*cosPhi en amperes
