ITC Midwest will be conducting aerial patrols of high-voltage transmission structures and lines throughout its service territory from approximately Sept. 27 through Oct. 8, weather permitting. Helicopter patrols provide an overall status of the overhead transmission system owned and operated by ITC Midwest.
The flights will be conducted in the regional communities of Fairmont, Jackson, Luverne and Sherburn. In addition, aerial patrols will take place in Jackson, Martin, Nobles and Rock counties.
These patrols are a North American Electrical Reliability Corporation (NERC) requirement for ITC Midwest’s vegetation management program, support proactive maintenance objectives, and align with the company’s model for operational excellence. They include inspections of steel structures, wood poles, conductors (wires), insulators and other equipment. Crews check for damaged or worn equipment and vegetation hazards.
The inspection flights are often conducted at low altitudes to allow accurate visual inspection of equipment for lightning damage, wear or other potential problems. This is normal procedure, so there is no cause for alarm if a low-flying helicopter is sighted near transmission lines during the time frame listed above.
