2. Engine–generator - Wikipedia

   en.wikipedia.org/wiki/Engine–generator

   An engine–generator is the combination of an electrical generator and an engine (prime mover) mounted together to form a single piece of equipment. This combination is also called an engine–generator set or a gen-set. In many contexts, the engine is taken for granted and the combined unit is simply called a generator. An engine–generator ...

3. Power factor - Wikipedia

   en.wikipedia.org/wiki/Power_factor

   For example, if the load power factor were as low as 0.7, the apparent power would be 1.4 times the real power used by the load. Line current in the circuit would also be 1.4 times the current required at 1.0 power factor, so the losses in the circuit would be doubled (since they are proportional to the square of the current).

4. Single-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Single-phase_electric_power

   Single phase power transmission took many years to develop. The earliest developments were based on the early alternator inventions of 19th century Parisian scientist Hippolyte Pixii, which were later expanded upon by Lord Kelvin and others in the 1880s. The first full AC power system, based on single phase alternating current, was created by ...

5. Electric generator - Wikipedia

   en.wikipedia.org/wiki/Electric_generator

   U.S. NRC image of a modern steam turbine generator (STG). 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.

6. Electric power distribution - Wikipedia

   en.wikipedia.org/wiki/Electric_power_distribution

   In the UK a typical urban or suburban low-voltage substation would normally be rated between 150 kVA and 1 MVA and supply a whole neighbourhood of a few hundred houses. Transformers are typically sized on an average load of 1 to 2 kW per household, and the service fuses and cable is sized to allow any one property to draw a peak load of perhaps ...

7. Volt-ampere - Wikipedia

   en.wikipedia.org/wiki/Volt-ampere

   The volt-ampere (SI symbol: VA, [1] sometimes V⋅A or V A) is the unit of measurement for apparent power in an electrical circuit. It is the product of the root mean square voltage (in volts) and the root mean square current (in amperes). [2] Volt-amperes are usually used for analyzing alternating current (AC) circuits.

8. Generator (circuit theory) - Wikipedia

   en.wikipedia.org/wiki/Generator_(circuit_theory)

   A generator in electrical circuit theory is one of two ideal elements: an ideal voltage source, or an ideal current source. [1] These are two of the fundamental elements in circuit theory. Real electrical generators are most commonly modelled as a non-ideal source consisting of a combination of an ideal source and a resistor.

9. Single-phase generator - Wikipedia

   en.wikipedia.org/wiki/Single-phase_generator

   In the figure, at the position where pole number 1 and coil number 1 meet, the generator produces the highest output voltage on one direction. As the rotor turns 180 degrees, the output voltage is alternated to produce the highest voltage on the other direction. [ 3 ]
