An underground power line provides electrical power with underground cables. Compared to overhead power lines, underground lines have lower risk of starting a wildfire and reduce the risk of the electrical supply being interrupted by outages during high winds, thunderstorms or heavy snow or ice storms. An added benefit of undergrounding is the ...
Steven Powell, the CEO of the utility company, insisted that the winds blowing through Eaton Canyon back on Jan. 7 weren't strong enough to warrant de-energizing the transmission line that is ...
Usually winds would have to be 60 to 80 mph for the company to consider the de-energization of transmission lines, Powell said, adding that the readings Edison saw were lower than that. The Eaton ...
In transmission line faults, roughly 5% - 10% are asymmetric line-to-line faults. [2] line-to-ground fault - a short circuit between one line and ground, very often caused by physical contact, for example due to lightning or other storm damage. In transmission line faults, roughly 65% - 70% are asymmetric line-to-ground faults. [2]
Stray voltage is the occurrence of electrical potential between two objects that ideally should not have any voltage difference between them. Small voltages often exist between two grounded objects in separate locations by the normal current flow in the power system.

Galloping conductors in eastern Idaho around Christmastime 1998. Conductor gallop is the high-amplitude, low-frequency oscillation of overhead power lines due to wind. [1] The movement of the wires occurs most commonly in the vertical plane, although horizontal or rotational motion is also possible.
“The stress from shoveling snow combined with the bitter cold can be dangerous, causing an increase in blood flow and blood pressure,” explains Dr. Patrick Kee, MD, Ph.D., a medical director ...
