A single-phase lateral is shown in Fig. 1 below having line impedance of 0.3+j0.6/mile. Fig. 1: Single phase lateral. The loads are, in units of kW+jkVAR: S1=1500+j750. S2=900+j500. The source voltage at node 1 is V1=7200V. Compute the node voltages at buses 2 and 3 to within a tolerance of 0.001pu.

(3) Power Factor Adjusted Monthly NCP kW demands will be used in determining the Billing kW under the applicable tariff schedule. If Company has a different power factor billing adjustment it shall conform to these calculations upon its next general rate case.
Three Phase Current - Simple Calculation
NEC 430-150, 10 HP @ 460V, 3 phase I = 14 Amp . KW, KVA. KW is real consumed power turned into heat, and is the product of volts x current x power factor. KVA is apparent power, is always greater than or equal to KW and is the product of volts x amps 1 phase, volts x amps x , (3, 3 phase. USE KVA for calculations unless load is resistive, (ie ...

Jul 30, 1999 · The total power in a three-phase balanced circuit, i.e., power delivered by a three-phase generator or absorbed by three-phase load is determined by adding the power in each of the three phases. In a balanced circuit this is the same as multiplying the power in any one phase by 3 since the power is the same in all phases.
