  2. Break-in (mechanical run-in) - Wikipedia

    en.wikipedia.org/wiki/Break-in_(mechanical_run-in)

    Break-in or breaking in, also known as run-in or running in, is the procedure of conditioning a new piece of equipment by giving it an initial period of running, usually under light load, but sometimes under heavy load or normal load. It is generally a process of moving parts wearing against each other to produce the last small bit of size and ...

  3. Sulfur hexafluoride circuit breaker - Wikipedia

    en.wikipedia.org/wiki/Sulfur_hexafluoride...

    A particular embodiment of the thermal blast technique has been developed and applied to generator circuit breakers. The self-blast technique described above is also widely used in SF 6 generator circuit breakers, in which the contact system is driven by a low-energy, spring-operated mechanism. An example of such a device is shown in the figure ...

    Rexburg flooded following Teton Dam failure. This is a list of major hydroelectric power station failures due to damage to a hydroelectric power station or its connections. . Every generating station trips from time to time due to minor defects and can usually be restarted when the defect has been remed

  5. Transfer switch - Wikipedia

    en.wikipedia.org/wiki/Transfer_switch

    An open transition transfer switch is also called a break-before-make transfer switch. A break-before-make transfer switch breaks contact with one source of power before it makes contact with another. It prevents backfeeding from an emergency generator back into the utility line, for example. [1]

  6. Heat recovery steam generator - Wikipedia

    en.wikipedia.org/wiki/Heat_recovery_steam_generator

    A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process ( cogeneration ) or used to drive a steam turbine ( combined cycle ).

  7. Thermoelectric generator - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_generator

    A thermoelectric generator (TEG), also called a Seebeck generator, is a solid state device that converts heat (driven by temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect [1] (a form of thermoelectric effect).

  8. British thermal unit - Wikipedia

    en.wikipedia.org/wiki/British_thermal_unit

    The Btu should not be confused with the Board of Trade Unit (BTU), an obsolete UK synonym for kilowatt hour (1 kW⋅h or 3,412 Btu). The Btu is often used to express the conversion-efficiency of heat into electrical energy in power plants. Figures are quoted in terms of the quantity of heat in Btu required to generate 1 kW⋅h of electrical energy.

  9. Radioisotope thermoelectric generator - Wikipedia

    en.wikipedia.org/wiki/Radioisotope...

    Diagram of an RTG used on the Cassini probe. A radioisotope thermoelectric generator (RTG, RITEG), sometimes referred to as a radioisotope power system (RPS), is a type of nuclear battery that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect.
