The rated voltage is the standard voltage for long-term stable operation of electrical equipment (including electricity and power supply equipment). When the operating voltage of the electrical equipment is higher than the rated voltage, it is easy to damage the equipment, and if it is lower than the rated voltage, it will not work normally.
The rated voltage can be understood from two aspects of the power equipment and the power supply equipment. The rated voltage of the power equipment represents the optimal input voltage designed when the equipment is shipped, and is usually a relatively easily obtained power supply voltage. The rated voltage of the power supply equipment represents the best output voltage of the power supply system and needs to be matched with the rated voltage of the power equipment, including the rated voltage of the power grid, the rated voltage of the generator and the rated voltage of the power transformer.
