Understand Electrical Power Engineering: How Power Grids Work· Electrical power starts at the power plant. In almost all cases, the power plant consists of a spinning electrical generator.Something has to spin that generator -- it might be a water wheel in a hydroelectric dam, a large diesel engine or a gas turbine.But in most cases, the thing spinning the generator is a steam turbine.The steam might be created by burning coal, oil or natural gas.
Transformer Basics and Transformer Principles Voltage Transformer can be thought of as an electrical component rather than an electronic component. A transformer basically is very simple static (or stationary) electro-magnetic passive electrical device that works on the principle of Faraday's law of induction by converting electrical energy from one value to another.
