Model Of A High Voltage Long Distance Line

Model HV-EXP2412
Principle When electrical energy is transmitted over long distances, it is unavoidable that there will be losses due to resistance in the lines. Using transformer stations and high-voltage transmission lines can drastically reduce such losses. To model such lines, two wires of 1 m in length and total resistance of 100 ohms are connected to a 6-V/0.5-A light bulb;and an AC voltage of;6 V is transmitted along them. Under these circumstances the lamp does not light. However, if two step transformers are set-up as transformer stations to increase the voltage in the simulated transmission lines to 1000 V and then convert it back down to 6 V immediately before the lamp, the lamp will light up with its normal brightness..
