The experiments show how changes in the source, the load, and the transmission line affect the overall performance of the system. In particular, they illustrate the meaning of real and reactive power, how the voltage at the end of a line can be lowered or raised, how power can be forced to flow over one line instead of another, how generators can be synchronized and how a system behaves when subjected to disturbances. Despite their small size, the employed economical, low-power, and safe electric alternators, motors, capacitors, reactors, resistors, meters, transformers, and transmission lines are designed to act in exactly the same way under steady-state and transient conditions, as their larger counter parts in industry.
