The output power of a generator is 10kW, the output voltage is 500V, the total resistance of the conductor is 5 Ω, the power loss is 5% of the total power, and the voltage required by the user is 220V. The turn ratio of step-up transformer and step-down transformer is calculated

The output power of a generator is 10kW, the output voltage is 500V, the total resistance of the conductor is 5 Ω, the power loss is 5% of the total power, and the voltage required by the user is 220V. The turn ratio of step-up transformer and step-down transformer is calculated

1. Since the step-up transformer is located at the generator and the step-down transformer is located at the user's place, if the loss of transformer is ignored, the lost power is all the loss on the conductor between the two places. The output power of generator = 10000w; the lost power = 10kW * 5% = 500W; the power obtained on load = 9500w

A generator, the output power is 100kW, the output voltage is 250V, then the output current is 250V______ A. When the generator works continuously for one day, the output power is______ kW•h．

Output power I = Pu = 100000w250v = 400A. Output power W = Pt = 100kW × 24h = 2400kw · H
