In electric power distribution, a busbar (also bus bar) is a metallic strip or bar, typically housed inside switchgear, panel boards, and busway enclosures for local high current power distribution. They are also used to connect high voltage equipment at electrical switchyards, and low-voltage equipment in battery banks .
Most of the world uses 50 Hz 220 or 230 V single phase, or 400 V three-phase for residential and light industrial services. In this system, the primary distribution network supplies a few substations per area, and the 230 V / 400 V power from each substation is directly distributed to end users over a region of normally less than 1 km radius.
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.
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:
Layout details and construction of electrical rooms will be controlled by local building code and electrical code regulations. Requirements for an electrical room relate to fire safety and electrical hazards.
