A transformer is a device used to transfer Electric power from one circuit at a certain voltage level to another circuit at a different voltage level. The electrical power is transferred by Magnetic Induction between two coils in the magnetic circuit of the transformer.
Control Systems - Introduction. A control system is a system, which provides the desired response by controlling the output. ... Here, a sequence of input signal is applied to this control system and the output is one of the three lights that will be on for some duration of time.
Transmission and distribution refers to the different stages of carrying electricity over poles and wires from generators to a home or a business. ... Transmission lines move large amounts of power at a high voltage level – a level that is too much to be delivered directly to a home or business.
Analysis of power systems is typically made using the method of either phase coordinates or symmetrical components depending on the type of network (un/symmetrical).
Power Electronics - Introduction. Power Electronics refers to the process of controlling the flow of current and voltage and converting it to a form that is suitable for user loads. The most desirable power electronic system is one whose efficiency and reliability is 100%.
