The Transmission Lines Model is able to easily and safely demonstrate the principles as to why electricity is stepped up to thousands of volts when transmitted over long distances. With no voltage step up, the power loss in the lines is significant and the consumer lamp doesn't glow. With voltage step up, the power loss in the lines is reduced and the consumer lamp glows.
Show safely and effectively why electricity is stepped up to 1,000s of volts when transported over large distances. Measure all currents and voltages in the power station, transmission lines and home. Compare the electricity loss (with step up) to the electricity loss (no step up). Four multimeters (capable of being used as an AC ammeter and AC voltmeter) and banana leads required. Instructions included.
