		f any unauthorized person intends to work within ten feet of any high voltage overhead electric utility line, the person responsible for the work to be done must notify the owner or operator of the high voltage overhead electric utility line not less than forty-eight hours prior to commencing work.
		As long as a bird is not touching anything but the power line, the bird and the line are at the same voltage, meaning they're both in the air.
		However, if a bird lands on a power line and touches another object such as a utility pole or a tree at the same time it is in contact with a power line, the bird gives electricity a path to the ground.

	Overhead powerline - Wikipedia, the free encyclopedia
		Today overhead lines are routinely operated at RMS voltages exceeding 765,000 volts between conductors, with even higher voltages possible in some cases.
		Along a staggered array line the conductor cables for the supply of the earth net of the transmitting antenna are attached on the exterior of a ring, while the conductor inside the ring, is fastened to insulators leading to the high voltage standing feeder of the antenna.
		The area under an overhead line can be used for most purposes, at which the danger does not exist that objects connected with the ground come into the proximity of the conductor cables or at which can be the danger that the conductor cables, insulators or mast constructions are damaged.

		We are very sorry that passengers recently experienced severe disruption due to overhead line problems and we understand the significant inconvenience these events caused.
		The cause of the disruption on 30 August was a fault with the component that allows the overhead lines to expand and contract in changing temperatures.
		Following a special joint inquiry, which took account of both passengers' criticisms and feedback from employees on duty on the relevant occasions, we have identified a set of initiatives which will be implemented to ensure that provision of information, alternative transport and assistance for passengers is improved in the event of any similar disruptive incidents.

		If an object (scaffolds, crane, etc.) must be moved in the area of overhead power lines, appoint a competent worker whose sole responsibility is to observe the clearance between the power lines and the object.
		When mechanical equipment is being operated near overhead power lines, employees standing on the ground may not contact the equipment unless it is located so that the required clearance cannot be violated even at the maximum reach of the equipment.
		This equipment may consist of rubber insulating gloves, hoods, sleeves, matting, blankets, etc. These items must be inspected prior to each use and tested annually.

	ACP Observer, March 2004 - Physicians try to rein in runaway overhead
		With practice overhead eating into physicians' revenue, practices are looking for ways to attack overhead, without cutting into the core services they offer patients.
		Because personnel costs account on average for about one-quarter of the operating costs of internal medicine practices, internists are looking for ways to cut their number of staff—or use their staff time more wisely.
		The flip side of cutting overhead is to maximize the revenue you can earn with those fixed and variable costs.

		The key signal at the centre of the Paddington rail tragedy could have been partly obscured by overhead line equipment, the second interim report into the disaster has said.
		The finding on signal 109 was revealed along with details from the "fl box" recorder which was recovered from the Thames train involved in the crash in west London on 5 October.
		The report said further testing of signal 109 and related equipment had reinforced the initial interim report's finding that signalling was not at fault.

	PB Network \| Issue 48 \| Fifty Years of Switching Station Design Development on AC Electrified Railways in the UK
		Between 1967 and 1973, the Glasgow-Gourock-Wemyss Bay line was electrified using outdoor oil-filled switchgear K11-W. The delivery of power to the OLE was through weatherproof bushings and the connection to the OLE was achieved by aerial bare-copper conductors.
		During the implementation of metal-clad switchgear design in the early 1970s, a critical decision was taken to transfer the isolation and earthing facilities from indoor environment to the track environment by installing track isolators and earthing switches on the OLE.
		Consequently, the end users of the equipment were unable to formulate an integrated maintenance strategy to deal with this change.
