Step 1: Employee
- Immediately notifies the Operator of loss of power while holding a Hot Line Hold.
- Reports to the Operator if assistance is needed and reports the events which caused the circuit to open, if known.
Note: It is required that the holder of the Hot Line Hold monitor the radio. - States if the line is clear to be reenergized. If clear, the employee shall release the Hot Line Hold.
Step 2: Operator
- Verifies with the employee that the line has opened. Responds to any assistance needed. Logs information.
- Confirms if the circuit is ready to be energized. Orders tag to be removed, recloser back to reclose and energizes circuit.Note: If the SCADA-controlled protective device relayed open, the Operator should place the device back to reclose operation immediately prior to closing to ensure that the fuse(s) in the field will operate. If the protective device is closed while on Hot Line Hold, (instantaneous relay operation), the device may relay open for a fault behind the fuse(s) or for cold load.
- If required, re-tag the affected device and re-issue the Hot Line Hold, to the employee.
