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. [4]
The engineering design work is expected to take two years, and the construction a further three years. SEPTA also plans to build a new substation near Woodbourne station by Fall 2020, as the distance between Neshaminy Falls and Yardley substations is nearly twice the optimal 5-mile (8.0 km) distance between substations on a 12 kV 25 Hz system ...
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 air-cooled load bank, being used for acceptance testing of a 3000 kW standby diesel generator set. This is one of three banks used to load the generator to verify performance on load changes and for factory run-in.
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 further measure of control is provided by using pairs of motors on a vehicle in series-parallel control; for slow operation or heavy loads, two motors can be run in a series of the direct-current supply. Where higher speed is desired, these motors can be operated in parallel, making a higher voltage available at each motor and so allowing ...
A 200 kW Caterpillar diesel generator set in a sound attenuated enclosure used as an emergency backup at a sewage treatment substation in Atlanta, United States. A diesel generator (DG) (also known as a diesel GenSet) is the combination of a diesel engine with an electric generator (often an alternator) to generate electrical energy. [1]
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 ...
