I got you on the differance between Hot-Line-Tag and non-reclose. Understand that only newer equipment has the hotline tag feature.
Your situation needs a code based argument to your management engineers and accountants. Goes like this. We have a feeder breaker and three normal open points. Automatic restoration scheeme is enables such that we have 4 possible sources to be disabled non-auto and tagged via scada by the way I read NESC.
NESC 442F requires for the protection of the field worker the circuits or equipment shall be left open until reclosing has been authorized.
Refer to rule 442E for the tagging requirement. If I'm working on a line and there are 4 possible divices that can auto reclose back into my work area I need to tag up all 4 devices by code. Take note on the exception as to this is how the hotline tag protocal via SCADA fits in.
442. Switching control procedures
E. Tagging electric supply circuits associated with work activities
1. Equipment or circuits that are to be treated as de-energized and grounded per Rule 444D shall have suitable tags attached to all points where such equipment or circuits can be energized.
2. When the automatic reclosing feature of a reclosing device is disabled during the course of work on energized equipment or circuits, a tag shall be placed at the reclosing device location.
EXCEPTION: If the automatic reclosing feature of a reclosing device is disabled by a Supervisory Control and Data Acquisition System (SCADA), the system shall provide for the following:
(a) At the SCADA operating point
(1) A signal is received by the SCADA operator confirming that the disabling operation has occurred at the reclosing device location, and
(2) A readily visible tag or electronic display is used to inform any potential SCADA operator that a disabling operation has been initiated, and
(3) The tag or electronic display is removed before action is taken to re-enable the automatic reclosing feature.
(b) At the reclosing device location
(1) The reclosing feature is disabled in such a manner as to prevent manual override of the normal control by any potential on-site operator, or
(2) A signal, flag, or other display is used in such a manner as to alert any potential on-site operator that the reclosing feature has been disabled.
3. The required tags shall be placed to clearly identify the equipment or circuits on which work is being performed.
