Electrical Substation
A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels. A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two different transmission voltages. They are a common component of the infrastructure, for instance there are 55,000 substations in the United States. Substations may be owned and operated by an electrical utility, or may be owned by a large industrial or commercial customer. Generally substations are unattended, relying on SCADA for remote supervision and control. The word ''substation'' comes from the days before the distribution system became a grid. As central generation stations became ...

Traction Substation
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 trolleybuses with traction current. Conversions These systems can be used to convert three-phase 50 Hz or 60 Hz alternating current (AC) for the supply of AC railway electrification systems at a lower frequency and single phase, as used by many older systems, or to rectify AC into direct current (DC) for those systems (primarily public transit systems) using DC for traction power. The three-phase voltage from the local utility is stepped down and rectified in the traction substations to provide the required DC voltage. Equipment Rotating Originally, the conversion equipment usually consisted of one or more motor-generator sets contain ...

Police Substation
A police station (sometimes called a "station house" or just "house") is a building which serves to accommodate police officers and other members of staff. These buildings often contain offices and accommodation for personnel and vehicles, along with locker rooms, temporary holding cells and interview/interrogation rooms. Names Large departments may have many stations to cover the area they serve. The names used for these facilities include: *Barracks for many American state police and highway patrol stations and in Ireland *District office, typically used by American state police forces like the California Highway Patrol, but also used by smaller departments like the Calgary Police Service *Precinct house, or precinct, for some urban police departments in the United States such as the New York City Police Department, Memphis Police Department, and Newark Police Department, where stations are in charge of precincts *Police house *Police office, especially in Scotland *Statio ...

The Substation
The Substation (Chinese: 电力站) is Singapore's first independent contemporary arts centre. It was founded in 1990 by Kuo Pao Kun. The Substation is centrally located in the city's civic district and was the first building under the National Arts Council's "Arts Housing Scheme". It officially opened on 16 September 1990. The Substation is a non-profit organisation and registered Institution of Public Character in Singapore, which relies on financial and in-kind support from the general public, commercial organisations and government ministries to cover the costs of operating and developing arts & educational programmes. The Board is chaired by Chew Kheng Chuan. History The site of The Substation, as its name suggests, was previously a power sub-station. The building dates from 1926. In 1950 the Public Utilities Board added a garden to house outdoor equipment. The sub-station ended its operations in the late 1970s and the building was left vacant. Throughout the 1980s ...
