Problem – Voltage drop • A 230 V radial distributor is 70 m long and has a resistance of 0.0008 Ω /m supply and return. Four loads A, B, C and D rated at 30, 45, 60 and 80 A are fed from the cable at distances of 20, 10, 15 and 25 m, respectively. Calculate the total current drawn from the supply, the current in the cable between each of the loads and the voltage at load D if all the loads are connected.
