Power distribution box calculation
Pe is the rated power
Kx is the need factor
cosO is the power factor
Pjs is computing power
Ijs is calculating current
Pe active power, Kx need coefficient, Pjs calculation power, Ijs calculation current. And CosΦ represents the power factor.
The relationship between them is as follows: Pj=KxPe. Ij=Pj/(1.732Ue*cosφ), ue=380V is the rated voltage.
Among them, 1.732 is the square root of 3; P=root 3×U×I×power factor;
