BGE BGE Emergency Response & Outage Management 2 — Questions and Answers
Question 1: In BGE's distribution system, what is the purpose of a sectionalizing switch?
- To measure voltage levels at a distribution transformer
- To isolate a faulted section of line while maintaining power to healthy sections (Correct answer)
- To regulate billing intervals for commercial customers
- To convert AC power to DC for battery storage
Correct 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.
Question 2: What does 'restoration priority' mean during a BGE major outage event?
- All customers are restored strictly in the order their outage was reported
- Critical facilities and upstream transmission faults are addressed before individual residential outages (Correct answer)
- Customers who have been without power the longest are always restored first
- Commercial accounts are always restored before any residential customers
Correct 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.
Question 3: What information must a BGE field crew relay to the system control center before opening a switch on an energized distribution line?
- Their scheduled lunch break and expected return time
- The switch ID, current load conditions, and confirmation that safe clearance distances are maintained (Correct answer)
- The account numbers of all customers in the affected segment
- The estimated material cost for completing the repair
Correct 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.
Question 4: What is a 'switching order' in BGE distribution operations?
- A purchase order for new switching equipment
- A formal written or electronic sequence of steps authorizing specific switching operations to safely isolate or restore circuits (Correct answer)
- A customer request to change their BGE rate schedule
- A work order for physically replacing a damaged switch
Correct 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.
Question 5: What does 'estimated restoration time' (ERT) represent in a BGE outage event?
- The time a customer originally called to report the outage
- BGE's best projection of when power will be restored based on damage assessment and crew availability (Correct answer)
- The number of hours remaining in the field crew's work shift
- A contractual guarantee of when service will be restored
Correct 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.
Question 6: What hazard does accidental 're-energization' present to BGE workers during outage restoration?
- Reduced electricity bills for nearby customers
- Unexpected energization of lines workers believe are de-energized, creating an electrocution hazard (Correct answer)
- Overloading the billing and OMS systems
- Interference with smart meter AMI communications
Correct 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.
