BGE Emergency Response & Outage Management Flashcards

In BGE's distribution system, what is the purpose of a sectionalizing switch?

Answer: To isolate a faulted section of line while maintaining power to healthy sections

Sectionalizing switches allow BGE operators to isolate the faulted segment and reroute power through alternate paths, minimizing the number of customers affected by a single fault.

What does 'restoration priority' mean during a BGE major outage event?

Answer: Critical facilities and upstream transmission faults are addressed before individual residential outages

BGE prioritizes transmission-level faults first because clearing them restores the most customers simultaneously, then addresses critical facilities, then works down to individual service restorations.

What information must a BGE field crew relay to the system control center before opening a switch on an energized distribution line?

Answer: The switch ID, current load conditions, and confirmation that safe clearance distances are maintained

Crews must communicate the switch identifier, confirm safe approach clearances, and verify load conditions with the control center to prevent unsafe switching operations or accidental energization.

What is a 'switching order' in BGE distribution operations?

Answer: A formal written or electronic sequence of steps authorizing specific switching operations to safely isolate or restore circuits

A switching order is a formal, sequenced document specifying exactly which switches to operate and in what order, ensuring circuits are safely isolated and restored with no steps missed.

What does 'estimated restoration time' (ERT) represent in a BGE outage event?

Answer: BGE's best projection of when power will be restored based on damage assessment and crew availability

ERT is BGE's projected restoration time based on damage scope, crew availability, and repair complexity — it is an estimate that may be updated as more information becomes available.

What hazard does accidental 're-energization' present to BGE workers during outage restoration?

Answer: Unexpected energization of lines workers believe are de-energized, creating an electrocution hazard

Accidental re-energization of a line that workers believe is de-energized is a leading cause of utility worker fatalities, which is why lockout/tagout and personal protective grounds are mandatory.
