From BGE:
BGE will be using a utility helicopter contractor (see photo depicting the type of helicopter to be used) to perform work on BGE electric transmission equipment, to include towers, poles and wires. Area residents and motorists may see the helicopter hovering near transmission power lines or following a flight path along electric transmission rights of way. The helicopter may be seen hovering over individual transmission lines for several minutes before moving to additional equipment. BGE is working to minimize disruption from the helicopter. Motorists and passersby are advised to use caution in the vicinity of the work and maintain focus on traffic.
Weather permitting, this work is scheduled to continue through early June (daylight hours)
Helicopter inspections will take place along BGE electric transmission rights of way in Anne Arundel County, Baltimore County and Harford County. BGE has approximately 1,300 circuit miles of high voltage overhead electric transmission lines in central Maryland.
The inspection is part of BGE’s focus on continued electric service reliability for customers. The helicopter will be used to photograph BGE electric towers and equipment. The helicopter provides an aerial perspective on equipment and allows BGE to inspect the system more efficiently than using ground inspections alone. BGE crews will also continue to inspect power lines and equipment from the ground. The aerial images and ground surveys will be reviewed by BGE to identify any worn or damaged equipment that then will be scheduled for repair or replacement.
