What is the process of sectionalizing?

• A. It allows most consumers to receive power and interrupts only the affected lateral
• B. It disconnects the entire feeder during a fault
• C. It increases voltage to the affected area
• D. It briefly disconnects service for all customers

Answer: (A)

Sectionalizing focuses on isolating a fault to a single section of a distribution feeder so the majority of customers stay energized. When a fault occurs, sectionalizers and reclosers work together to open only the switches that enclose the affected lateral. This confines the outage to that specific segment while allowing the rest of the feeder to continue supplying power. Once the fault is cleared, the healthy parts of the feeder can be restored, minimizing overall customer impact.

This is why the described scenario fits best: most customers continue to receive power, and only the affected lateral is interrupted. The other ideas describe disconnecting the entire feeder, increasing voltage, or briefly interrupting service for all customers, none of which aligns with the purpose and outcome of sectionalizing.
