The voltage protection is a protective relaying method that protects the measured voltage of the device installation. The relay protection using the voltage too low or too high is called low-voltage protection and over-voltage protection. The operating voltage of the power system is an important indicator of power quality. When it deviates from the rated voltage by more than a certain limit, it may damage the stable operation of the system, affect the quantity and quality of factory products, and may also cause damage to electrical equipment.
