Assume that a three-phase 4.16 kV wye-grounded feeder main has #4 copper conductors with an equivalent spacing of 37 in. between phase conductors and a lagging-load power factor of 0.9. a. Determine the K constant of the main by employing Equation 4.77. b. Determine the K constant of the main by using the precalculated percent voltage drop per kilovolt-ampere-mile curves and compare it with the one found in part (a). K= Equation (4.77) (rcos+xsin)((1/3)×1000) V,VB Assume that a three-phase 4.16 kV wye-grounded feeder main has #4 copper conductors with an equivalent spacing of 37 in. between phase conductors and a lagging-load power factor of 0.9. a.
