  2. Load bank - Wikipedia

    en.wikipedia.org/wiki/Load_bank

    A load bank is a piece of electrical test equipment used to simulate an electrical load, to test an electric power source without connecting it to its normal operating load. [ 1 ] [ 2 ] During testing, adjustment, calibration, or verification procedures, a load bank is connected to the output of a power source, such as an electric generator ...

  3. Dummy load - Wikipedia

    en.wikipedia.org/wiki/Dummy_load

    A dummy load is a device used to simulate an electrical load, usually for testing purposes. In radio a dummy antenna is connected to the output of a radio transmitter and electrically simulates an antenna , to allow the transmitter to be adjusted and tested without radiating radio waves .

  4. Droop speed control - Wikipedia

    en.wikipedia.org/wiki/Droop_speed_control

    Droop speed control is a control mode used for AC electrical power generators, whereby the power output of a generator reduces as the line frequency increases. It is commonly used as the speed control mode of the governor of a prime mover driving a synchronous generator connected to an electrical grid. It works by controlling the rate of power ...

    en.wikipedia.org/wiki/Open-circuit_test

    Circuit diagram for open-circuit test. The open-circuit test, or no-load test, is one of the methods used in electrical engineering to determine the no-load impedance in the excitation branch of a transformer. The no load is represented by the open circuit, which is represented on the right side of the figure as the "hole" or incomplete part of ...

    The "1.2/50 μs" generator is designed for insulation testing, and produces a high-voltage, low-current impulse into a high-impedance load. The output current of this generator is on the milliampere scale. [2] [5] The "8/20 μs" generator is designed for surge arrester testing, and produces a high-current surge into a low-impedance load. [2]
