Most commonly, the utility does the engineering and procurement while hiring a contractor for actual construction. [3] Major design constraints for construction of substations include land availability and cost, limitations on the construction period, transportation restrictions, and the need to get the substation running quickly.

A time–distance diagram is a chart with two axes: one for time, the other for location. The units on either axis depend on the type of project: time can be expressed in minutes (for overnight construction of railroad modification projects such as the installation of switches) or years (for large construction projects); the location can be (kilo)meters, or other distinct units (such as ...
Engineering or Construction vehicles are heavy-duty vehicles, specially designed for executing construction (Civil engineering) tasks, most frequently, ones involving earth moving. Listed here are articles about the engineering vehicles themselves, their tools and their systems. Also notable manufacturers are listed.
An HVDC converter station (or simply converter station) is a specialised type of substation which forms the terminal equipment for a high-voltage direct current (HVDC) transmission line. [1] It converts direct current to alternating current or the reverse. In addition to the converter, the station usually contains:
A traction substation, traction current converter plant, rectifier station or traction power substation (TPSS) is an electrical substation that converts electric power from the form provided by the electrical power industry for public utility service to an appropriate voltage, current type and frequency to supply railways, trams (streetcars) or ...
Electricity generation covers the selection, design and construction of facilities that convert energy from primary forms to electric power. Electric power transmission requires the engineering of high voltage transmission lines and substation facilities to interface to generation and distribution systems.
Dead-end towers may be used at a substation as a transition to a "slack span" entering the equipment, when the circuit changes to a buried cable, when a transmission line changes direction by more than a few degrees, or at intervals along a straight run to limit the extent of a catastrophic collapse. Strain pylons and an anchor gantry
The IEEE 693: Recommended Practice for Seismic Design of Substations. [ 1 ] is a Institute of Electrical and Electronics Engineers standard. This standard is recognized also by American National Standards Institute , and is used mainly in the American Continent.
