A low voltage distribution transformer feeds two different loads with a three-phase line. The nominal voltage of the line is 400 Volt. The total length of the feeder is 500 m. The distance from the transformer to these loads is 140 m and 340 m, respectively. Their consumption is 11 kVA with a 0.8 lagging power factor and 10 kW with a 0.8 lagging power factor, respectively. The feeder's cross-section is 15 mm2 and the feeder's conductivity is 56 m/ohm.mm2. Find the following information. The distance from the transformer to the maximum voltage drop point is The maximum voltage drop is Volt The power loss between the transformer and 11 kVA load is Watt.
