2. Turbo generator - Wikipedia

   en.wikipedia.org/wiki/Turbo_generator

   A turbo generator is an electric generator connected to the shaft of a turbine (water, steam, or gas) for the generation of electric power. [ note 1 ] Large steam-powered turbo generators provide the majority of the world's electricity and are also used by steam-powered turbo-electric ships.

4. Grid-tie inverter - Wikipedia

   en.wikipedia.org/wiki/Grid-tie_inverter

   Grid-tie inverters are used between local electrical power generators: solar panel, wind turbine, hydro-electric, and the grid. [ 1 ] To inject electrical power efficiently and safely into the grid, grid-tie inverters must accurately match the voltage, frequency and phase of the grid sine wave AC waveform .

5. Split-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Split-phase_electric_power

   In a so-called balanced power system, sometimes called "technical power", an isolation transformer with a center tap is used to create a separate supply with conductors at balanced voltages with respect to ground. The purpose of a balanced power system is to minimize the noise coupled into sensitive equipment from the power supply.

   The system consisted of one or two letters followed by 3 or 4 digits. It was phased out after 1934 when Valvo adopted the Mullard–Philips scheme. First letter(s): Type [24] A – Triode; AN – Binode, a diode/triode or diode/tetrode; G – Rectifier; H – RF tube; L – Power tube; LK – Power amplifier; U – Triode with a space charge grid

9. Mains electricity - Wikipedia

   en.wikipedia.org/wiki/Mains_electricity

   Mains electricity, utility power, grid power, domestic power, wall power, household current, [2] or, in some parts of Canada, hydro, is a general-purpose alternating-current (AC) electric power supply. It is the form of electrical power that is delivered to homes and businesses through the electrical grid in many parts of the world. People use ...
