The relevant industry standards specify that its power distribution system must be provided with emergency power supplies. As another example of a data center, the absence of a supply voltage means the loss of data. People use a dual power transfer switch and an Uninterruptible Power Supply (UPS) to supply power in combination so as to ensure the continuity of the power supply.
However, since the neutral line is temporarily disconnected from the other phase lines during the switching process of the power supply, this causes fluctuations in the voltage of some consumers and thus causes influences and losses. For example, in the application of an uninterruptible power supply of a data center powered by a combination of an ASTE and a UPS, the short disconnection of the neutral line causes the zero-voltage of the UPS to rise and causes the server to restart, resulting in serious consequences such as data loss or server damage.
