Appendix 9C: Design Calculations for Electrical Design
Real Power W = V x I x pf Phase Angle θ = arctan(W/VARS) Power Factor pf = W/(V x I) = W/VA Voltage Drop V ( ) d =2× I ×R×cosθ+I ×X ×sinθ where : Vd = voltage drop in circuit sinθ = load reactive factor X = reactance 5.4 ALTERNATING CURRENT (AC), THREE-PHASE V denotes line to line voltage. Basic Formulas Apparent Power kVA =(V I× 3)
