Which action best describes restoring service after a fault by using alternate paths?

• A. Re-routing current to unfaulted circuits
• B. Increasing load on the faulted path
• C. Ventilating the switchgear
• D. Ignoring the fault

Answer: (A)

Restoring service after a fault by using alternate paths is about reconfiguring the network so loads are fed from unfaulted circuits. When a fault occurs, protective devices isolate the damaged section, and operators or automatic schemes switch power to healthy routes—feeding the same customers through different feeders or a different bus. This keeps the system energized and minimizes outage time while the fault is cleared or the faulty equipment is repaired. Pushing more load onto the faulted path would drive current through the problem area, risking further damage or a bigger outage. Ventilating the switchgear is a safety/pressure-relief action during a fault, not a method to restore service. Ignoring the fault leaves the system without power and unnecessary risk.
