Can the replacement capacitor in the low-voltage distribution room be used under load?

When replacing the capacitor in the low-voltage distribution room, it is best to run with no load. This is because replacing the capacitor will involve a power-off operation. If it is replaced with load, it may lead to sudden change of current or unstable voltage, which will affect or even damage equipment and power grid.

In addition, when replacing the capacitor, it should be operated according to the relevant safety regulations, such as cutting off the power supply, carrying out live measurement and discharge treatment to ensure safe operation.

If it is necessary to replace the capacitor with load, it is suggested to replace it in parallel at the load end, and pay attention to reasonable current distribution and protection measures. The specific operation needs to be determined according to the specific situation and equipment requirements, and it is best to consult professionals for safe and accurate operation.

In short, in order to ensure the safe operation and normal operation of the equipment, it is best to run with no load when replacing the capacitor.
