PECO has completed its annual inspection of more than 1,800 circuits and more than 10,000 miles of aerial electric lines across the service territory as part of the company’s maintenance and reliability improvement program. PECO invested about $600,000 to perform the inspections.

The program includes a visual examination of PECO’s aerial electric system throughout the service territory for issues such as damaged equipment and sagging lines. Infrared cameras also are used to identify potential equipment problems before they occur by recording the temperature variations within a piece of equipment while it is in operation. Equipment and lines in need of repair are reported throughout the inspection process and prioritized for repair based on the severity of the issue.

“Preventative maintenance programs help us identify and address potential equipment issues before they occur and improve the performance of our entire electric distribution system,” said John McDonald, vice president of Technical Services. “Each year we invest millions of dollars to continuously monitor, inspect, repair and replace equipment, which is crucial to ensuring that we keep the lights on for our customers.”

These inspections are part of PECO’s overall preventative maintenance program, which includes regular inspection of equipment on the company’s natural gas and electric systems, including manholes, underground cables, transformers, substations and other electrical equipment.
