Concord power outage caused by equipment malfunction


CONCORD, NC (FOX 46) — Concord Electric Systems crews continue to repair damage that occurred overnight in the City’s western service area.

The cause of Tuesday’s outage was an equipment malfunction combined with high moisture levels during the overnight fog, leading to arcing conditions at a power delivery point.

The City’s equipment properly de-energized the circuit, causing 5,400 customers to lose power.

The City was first aware of unusual activity on one of its major transmission circuits at 2:24 a.m., when some customers might have noticed some flickering. The main outage occurred at 5:25 a.m., when the circuit breaker opened to halt the arcing conditions.

On-call crews were dispatched to the location, and other resources were called in to verify the condition of the entire transmission circuit.

The lack of rain in the area led to contaminants remaining on the equipment, which contributed to the malfunction. The City is exploring cleaning methods to avoid similar problems in the future.

Given the voltage of the transmission circuit, crews took extra precautions to ensure all remaining equipment on the circuit was functioning properly before rerouting from the open breaker to an alternate breaker. Crews began to restore power at 9:30 a.m. Tuesday and by 9:41 power to all 5,400 customers was restored, with a total outage time of 4 hours and 16 minutes.
