A switching station is a substation without transformers and operating only at a single voltage level. Switching stations are sometimes used as collector and distribution stations. Sometimes they are used for switching the current to back-up lines or for parallelizing circuits in case of failure.
Step-down substation: these transformers lower the voltage coming from the transmission lines which can be used in industry or sent to a distribution substation. Distribution substation: these transform the voltage lower again for the distribution to end users. Aside from transformers, other major components or functions of substations include:
The term switching station may refer to: an electrical substation, with only one voltage level, whose only function are switching actions. a battery switch station, such as the ones used by the Better Place network. a railroad switching station. a telephone switching station
Step-down transmission substations are located at “switching points” in the power grid, connecting various parts of the grid and serving as a source of power for subtransmission lines — the ...
Low-voltage side switching cabinet of a European MV/LV substation. Four LV cable feeders equipped with circuit breakers featured. Power-system protection in radial networks is simple to design and implement, since short-circuit currents have only one possible path that needs to be interrupted.
In electricity distribution networks, spot network substations (network transformers) are used in interconnected distribution networks. They have the secondary network (also called a grid network) with all supply transformers bussed together on the secondary side at one location.
In an electric power transmission grid system, switchyard reactors are large inductors installed at substations to help stabilize the power system. For transmission lines, the space between the overhead line and the ground forms a capacitor parallel to transmission line, which causes an increase in voltage as the distance increases.
The three-phase alternating current switch gear of a converter station is similar to that of an AC substation. It will contain circuit breakers for overcurrent protection of the converter transformers, isolating switches, grounding switches, and instrument transformers for control, measurement and protection.
