Low pressure of medical equipment

The grid voltage drops to 70%, and the duration depends on the specific reasons and location. If the voltage drops suddenly due to sudden load change or line fault, it usually lasts for a short time, maybe only a few milliseconds or seconds. However, if the overall voltage of the power grid drops due to large-scale power outages and natural disasters, it may last longer, even hours or days. In addition, the voltage drop of the power grid will have a certain impact on power equipment and electrical equipment. In the case of voltage drop, all kinds of electrical equipment may fail or be damaged, especially some equipment with high voltage requirements (such as computers and medical equipment). ), it is easily affected. Therefore, in practical application, it is necessary to detect and deal with the grid voltage drop event in time through power system monitoring technology to ensure the stable and reliable operation of the power system.
