Automation through an Auto Trip Console: Give precise control and optimize the power distribution.
+Automation eliminates dependency on local operators for feeder control.
+Equipping dedicated 11kV feeders with automatic devices ensures precise operation.
+Malpractice prevention: Device blocks attempts to recharge feeders before preset time.
+Feeder remains off until the preset recharge time is reached, ensuring compliance.
