Question
Consider the below secondary system MV.CBD Primary DT 200KVA 20KV-220/380V LV.CB Outdoor temperature t=40°c Secondary main XLPE direct in air L-AB=150m FACTORY BUILDING Indoor temperature t=30 C SD1 C 30 E SD3 30 B L-BE=100m On cable tray 50KW L-BC=60m 50KVA in conduit PVC XLPE L-BD-40m in duct XLPE SD2 30 D 50HP where all loads are lagging with PF=0.8. The table of conductor parameters is as follow Conductor size 16 mm2 25 mm2 35 mm2 Ampacity / phase R (N /km) X (Q /km) 50A 0.7 0.07 63A 0.6 0.06 80A 0.5 0.05 50 mm2 100A 0.4 0.04 70 mm2 140A 0.3 0.03 95 mm2 180A 0.2 0.02 120 mm2 150 mm2 250A 0.1 0.01 350A 0.09 0.009 Assuming that correction factor K=0.7 for all loads. From B to E, the size of cable per phase (S) and the percentage voltage drop (%VD) will be: Select one: O a. S= 50mm? & %VD = 2.99% Ob. S= 70mm? & %VD = 1.199% Oc. S= 95mm? & %VD = 1.99% O d. None of these O e. S= 95mm? & %VD = 0.93% O f. S= 70mm? & %VD = 0.99%
