PROVIDENCE, R.I. (WPRI) — The region’s primary utility operator, National Grid, says its inspectors are taking to the air Wednesday to look over the conditions of “subtransmission” electric lines after recent powerful thunderstorms. Inspectors will employ helicopters to go airborne and look down upon the power lines to see how they’re doing.

“Subtransmission lines” generally carry electricity of 69,000 volts or below, and typically deliver power among substations.

The power company said Wednesday it’s a regular practice for them to visually inspect lines by helicopter to address potential problems before it impacts customers’ electric service. Inspectors are looking for broken wires, cracked insulators, signs of wear or trees leaning too close to the lines or poles.
