2. Single-line diagram - Wikipedia

   en.wikipedia.org/wiki/Single-line_diagram

   A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.

3. Transfer switch - Wikipedia

   en.wikipedia.org/wiki/Transfer_switch

   3-phase transfer switch single-line diagram Intelligent transfer switch. A transfer switch is an electrical switch that switches a load between two sources. Some transfer switches are manual, in that an operator effects the transfer by throwing a switch, while others are automatic and trigger when they sense one of the sources has lost or gained power.

4. Single-phase generator - Wikipedia

   en.wikipedia.org/wiki/Single-phase_generator

   Single-phase generator (also known as single-phase alternator) is an alternating current electrical generator that produces a single, continuously alternating voltage. Single-phase generators can be used to generate power in single-phase electric power systems. However, polyphase generators are generally used to deliver power in three-phase ...

5. Electric generator - Wikipedia

   en.wikipedia.org/wiki/Electric_generator

   In electricity generation, a generator[1] is a device that converts motion-based power (potential and kinetic energy) or fuel-based power (chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even ...

6. Electric power system - Wikipedia

   en.wikipedia.org/wiki/Electric_power_system

   An electric power system is a network of electrical components deployed to supply, transfer, and use electric power. An example of a power system is the electrical grid that provides power to homes and industries within an extended area. The electrical grid can be broadly divided into the generators that supply the power, the transmission ...

7. Static VAR compensator - Wikipedia

   en.wikipedia.org/wiki/Static_VAR_compensator

   Static VAR compensator. In Electrical Engineering, a static VAR compensator (SVC) is a set of electrical devices for providing fast-acting reactive power on high-voltage electricity transmission networks. [1][2] SVCs are part of the flexible AC transmission system [3][4] device family, regulating voltage, power factor, harmonics and stabilizing ...

8. Symmetrical components - Wikipedia

   en.wikipedia.org/wiki/Symmetrical_components

   By expanding a one-line diagram to show the positive sequence, negative sequence, and zero sequence impedances of generators, transformers and other devices including overhead lines and cables, analysis of such unbalanced conditions as a single line to ground short-circuit fault is greatly simplified. The technique can also be extended to ...

9. Power-flow study - Wikipedia

   en.wikipedia.org/wiki/Power-flow_study

   In power engineering, the power-flow study, or load-flow study, is a numerical analysis of the flow of electric power in an interconnected system. A power-flow study usually uses simplified notations such as a one-line diagram and per-unit system, and focuses on various aspects of AC power parameters, such as voltages, voltage angles, real power and reactive power.
