Abstract Power quality as well as the reliability of power supply has always been the matters considered by both the users and the electrical designers. It is likely that most of the designers engaged in electrical design of public building do not pay much attention to the impact and hazards of voltage sag；thus，it is difficult for them to gain a clear idea of the impact of a voltage sag in certain place of the power supply system. This paper elaborates the main hazards of voltage sag as well as the solutions based on an instance of certain airport engineering.
