The rectangular area in Figure 3.26 has a uniform load density of 2000 kVA/mile' at 0.9 lagging power factor. The nominal voltage of the area being served is 4.16 kV. The three-phase primary main conductors are 556,500 26/7 ACSR, while the three-phase lateral conductors are 266,800 26/7 ACSR. The primary main and the laterals are constructed so that the equivalent spacing (D) is 3.5 ft. Determine: 1. The % voltage drop to the last customer in the first lateral (point A). 2. The % voltage drop to the last customer in the last lateral (point B). 3. The total three-phase power loss for the total area. 2,500' Source 2,500 12,000' The rectangular area in Figure 3.26 has a uniform load density of 2000 kVA/mile' at 0.9 lagging power factor.
