  2. National Electrical Safety Code - Wikipedia

    en.wikipedia.org/wiki/National_Electrical_Safety...

    The National Electrical Safety Code (NESC) or ANSI Standard C2 is a United States standard of the safe installation, operation, and maintenance of electric power and communication utility systems including power substations, power and communication overhead lines, and power and communication underground lines.

  3. Overhead power line - Wikipedia

    en.wikipedia.org/wiki/Overhead_power_line

    Overhead lines or overhead wires are used to transmit electrical energy to trams, trolleybuses or trains. Overhead line is designed on the principle of one or more overhead wires situated over rail tracks. Feeder stations at regular intervals along the overhead line supply power from the high-voltage grid.

  4. Overhead line - Wikipedia

    en.wikipedia.org/wiki/Overhead_line

    The installation of overhead lines may require reconstruction of bridges to provide safe electrical clearance. [20] Overhead lines, like most electrified systems, require a greater capital expenditure when building the system than an equivalent non-electric system. While a unelectrified railway line requires only the grade, ballast, ties and ...

  5. Live-line working - Wikipedia

    en.wikipedia.org/wiki/Live-line_working

    Bare-hand, or potential working involves placing the worker in direct electrical contact with an energized overhead line. The worker might work alongside the lines, from a platform that is suspended from them, or may sit or stand directly on the line itself. [3] In all cases, the worker's body is maintained at the same voltage as the line.

  6. Overhead line crossing - Wikipedia

    en.wikipedia.org/wiki/Overhead_line_crossing

    An overhead line crossing is the crossing of an obstacle—such as a traffic route, a river, a valley or a strait—by an overhead power line.The style of crossing depends on the local conditions and regulations at the time the power line is constructed.

  9. Fuse cutout - Wikipedia

    en.wikipedia.org/wiki/Fuse_cutout

    In electrical distribution, a fuse cutout or cut-out fuse (often referred to as a cutout) is a combination of a fuse and a switch, used in primary overhead feeder lines and taps to protect distribution transformers from current surges and overloads. An overcurrent caused by a fault in the transformer or customer circuit will cause the fuse to ...
