BGE Grid Reliability & Infrastructure 3

Question 1

During a major storm event, BGE prioritizes restoration in which order?

Accepted Answer

Transmission → distribution substations → feeders → individual services

Answer

BGE follows a systematic priority: restore transmission, then distribution substations, then feeders serving critical facilities, then individual services.

Question 2

What is an Underground Residential Distribution (URD) cable's main advantage over overhead lines?

Accepted Answer

Greater resistance to weather-related outages

Answer

Underground cables are shielded from wind, ice, and tree contact, making them far less susceptible to storm-related outages compared to overhead lines.

Question 3

A substation transformer has an OLTC (On-Load Tap Changer). What does this device do?

Accepted Answer

Adjusts transformer turns ratio without de-energizing to regulate voltage

Answer

An OLTC allows operators to change the transformer tap position while it is energized and loaded, enabling voltage regulation without an outage.

Question 4

BGE is part of which regional transmission organization (RTO)?

Accepted Answer

PJM Interconnection

Answer

BGE operates within the PJM Interconnection, the RTO that coordinates wholesale electricity markets and grid reliability for the Mid-Atlantic and Midwest regions.

Question 5

What is the purpose of a sectionalizer on a distribution circuit?

Accepted Answer

Count fault current pulses and open automatically after a recloser locks out

Answer

A sectionalizer counts the number of fault-current pulses from an upstream recloser and opens after a preset count, isolating the faulted section without interrupting unfaulted sections.
