    Abstract: The test power supply system and its main equipment for the short-term withstand current of the switching device are introduced. The best selection method of test equipment capacity is analyzed. According to the requirements of different test product impedance and test current, the application examples of two power supply modes of power grid and short-circuit generator are selected, and the selection of test equipment and the calculation of corresponding test current are carried out. Among them, the change of impedance in different gears of the voltage regulating transformer and the test current under the forced excitation mode of the short-circuit generator are calculated in detail, which has reference value for future engineering applications.
    Key words: short-time withstand current; test power supply; equipment capacity selection; force excitation
