cosΦ In AC circuits, the cosine of the phase difference (Φ) between the voltage and the current is called the power factor, which is represented by the symbol cosΦ. Numerically, the power factor is the ratio of the active power to the apparent power, i.e., cosΦ=P/S
Calculated load Pjs=PE*Kc; Calculated current Ijs=Pjs/(u*cos&) This is a single-phase, three-phase more divided by the root 3.
08D800-1 atlas, 4 circuit, 0.95,6 circuit 0.8, so KC=0.9, a single circuit is 1
Pjs=PE*Kc=12*0.9=10.8kw, the capacity of the equipment. 10.8kw, the sum of equipment capacity 9kw, cosΦ=P/S=9/10.8 is about 0.8
