Description & Specification:

Model Of A High Voltage Long Distance Line For Electrical Lab Training.
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.
