General Electric Energy Supply Process

Process of supplying electrical energy in general: Conversion (generation) → Transmission → Distribution.

Electrical Conversion

Conversion in the field of electric power is the conversion from other energy to electrical energy. This conversion is usually used to generate electricity, producing this electricity is called a generator, in other words as a producer. Here are example sources of electrical energy: Hydroelectric Power Plant, Steam Power Plant, Nuclear Power Plant, Gas Power Plant, and Diesel Power Plant. Other generators include: Solar Power, Wind Power, Chemical Reactions, Geothermal Energy and others.

Nuclear Energy etc → Reactor Converter etc → Alternate → Transformer Step Up; Reactor Converter etc → Generate

Electric Transmission

Electric transmission is the process of sending electricity. The delivery goes through the power grid.

Step-Up Transformer → High Voltage Network → Step-Down Transformer → Medium Voltage Network → Factory

Electricity Distribution

Electricity distribution is the process of sharing electricity to consumers.

Medium Voltage Network → Step-Down Transformer → Low Voltage Network → Consumer

DC (Direct Current) electric graph, V(t) = 2 volt, V(0) = 0 volt

AC (Alternating Current) electric graph, V(t) = sin(wt)
