2. Tachometer - Wikipedia

   en.wikipedia.org/wiki/Tachometer

   A tachometer on a tractor, reading up to 3000 RPM, with the hour meter below it showing 772.9 hours. The mark at 2500 RPM is the engine speed required to run the power take-off at 540 RPM. Traffic engineering

   Signal generator: Generates signals for testing purposes Spectrum analyser: Displays frequency spectrum Sweep generator: Creates constant-amplitude variable frequency sine waves to test frequency response Transistor tester: Tests transistors Tube tester: Tests vacuum tubes (triode, tetrode etc.) Wattmeter: Measures power in a circuit Vectorscope

4. Synchronization (alternating current) - Wikipedia

   en.wikipedia.org/wiki/Synchronization...

   The sequence of events is similar for manual or automatic synchronization. The generator is brought up to approximate synchronous speed by supplying more energy to its shaft - for example, opening the valves on a steam turbine, opening the gates on a hydraulic turbine, or increasing the fuel rack setting on a diesel engine. The field of the ...

5. Hobbs meter - Wikipedia

   en.wikipedia.org/wiki/Hobbs_meter

   A Hobbs Meter made by General Electric about 1970. Hobbs meter is a generic trademark for devices used in aviation to measure the time that an aircraft is in use. The meters typically display hours and tenths of an hour, but there are several ways in which the meter may be activated: It can measure the time that the electrical system is on.

6. Automatic generation control - Wikipedia

   en.wikipedia.org/wiki/Automatic_generation_control

   An electrical grid may have many types of generators and loads; generators must be controlled to maintain stable operation of the system. In an electric power system, automatic generation control (AGC) is a system for adjusting the power output of multiple generators at different power plants, in response to changes in the load. Since a power ...

7. Diesel generator - Wikipedia

   en.wikipedia.org/wiki/Diesel_generator

   A specific model of a generator operated as a standby generator may only need to operate for a few hours per year, but the same model operated as a prime power generator must operate continuously. When running, the standby generator may be operated with a specified - e.g. 10% overload that can be tolerated for the expected short running time.
