What Happens After A High-voltage Disconnect Switch Isolates Line Equipment From The Power Supply?

High Voltage Disconnect Switch can isolate line equipment from the power supply. Once the equipment is isolated, it loses its electrical connection with the system power supply, allowing subsequent maintenance work to be carried out in a power-off state, thus achieving operational safety. In other words, the electric field and loop current between the line equipment and the power supply are cut off, and the equipment is in a "power-off" state. This principle is widely used in substations and high-voltage power distribution systems.
