Helicopter Inspections Planned for Power Lines

The following announcement is from National Grid:

National Grid will take to the skies in the coming days, weather permitting, to conduct annual patrols of some key overhead power lines in several Massachusetts communities, including Attleboro and Seekonk. In addition to the annual flights, many of these lines were inspected in 2011 immediately following Tropical Storm Irene and the late October snowstorm.

The helicopter patrols help the company spot potential problems with equipment structures or lines so that they can be addressed before service interruptions occur.

Many of the power lines, which are major supply circuits, traverse remote areas that are difficult to access with vehicles, or on foot. The aerial view gained from a flyover also enables crews to spot potential problems with trees or tree limbs that may be too close to lines. Damage caused by falling trees of limbs can be a major cause of power outages.

Additionally, inspectors conduct visual and infra-red inspections for general infrastructure wear and tear. The infra-red camera detects heat and is helpful in pinpointing areas where equipment wear or loose connections literally create visible "hot spots." Once problem areas are identified, crews are dispatched to make any required repairs.

National Grid has notified police and fire departments as well as municipal officials in communities where the patrols will take place. Anyone with questions or concerns 800-322-3223.
