The Importance Of Disconnecting The Line Before Operating A High-voltage Disconnect Switch
Date: | Read: 1
When power lines are energized, any attempt to operate High Voltage Disconnect Switch equipment may cause an arc flash, posing significant risks to both equipment integrity and operator safety.
In high-voltage power systems, the primary function of high-voltage disconnect switches is to isolate circuits, providing a safe environment for maintenance and inspection work. If operations are performed before the circuit is fully disconnected, current may still flow through the disconnect switch, causing arc flashes or equipment damage. Such incidents not only compromise the stability of power equipment but may also trigger more severe power failures.
