Pacific Electric Sub-Station No. 14
The Pacific Electric Sub-Station No. 14 is a former traction substation in Santa Ana, California. It was built by the Pacific Electric Railway to provide electricity to run the railway's streetcars in central Orange County, California. The building was added to the National Register of Historic Places in 1983. Substation function Electric trolley and interurban cars required 600 volts direct current (DC) to operate a car's DC traction motors. The function of a "substation" was to convert very high voltage alternating current (AC) from a power station, often miles away, for the necessary conversion to a lower voltage DC. High voltage AC entered the substation, was dropped to a lower voltage by a transformer, and then fed to a device called a Rotary Converter for the conversion to 600 volts DC. Substations were required on every trolley and interurban line in the United States and often still are for today's subway and light rail lines. Later the very large and cumberso ...

Santa Ana, California
Santa Ana () is the second most populous city and the county seat of Orange County, California. Located in the Greater Los Angeles region of Southern California, the city's population was 310,227 at the 2020 census, making Santa Ana the List of California cities by population, 13th-most populous city in California and the List of United States cities by population density, 4th densest large city in the United States (behind only New York City, San Francisco, and Boston). Santa Ana is a major regional economic and cultural hub for the Orange Coast. Santa Ana's origins began in 1810, when the Spanish governor of California granted Rancho Santiago de Santa Ana to José Antonio Yorba. Following the Mexican War of Independence, the Yorba family ranchos of California, rancho was enlarged, becoming one of the largest and most valuable in the region and home to a diverse Californio community. Following the American Conquest of California, the rancho was sold to the Sepúlveda family, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solid-state Electronics
Solid-state electronics means semiconductor electronics: electronic equipment using semiconductor devices such as transistors, diodes and integrated circuits (ICs). The term is also used as an adjective for devices in which semiconductor electronics that have no moving parts replace devices with moving parts, such as the solid-state relay in which transistor switches are used in place of a moving-arm electromechanical relay, or the solid-state drive (SSD) a type of semiconductor memory used in computers to replace hard disk drives, which store data on a rotating disk. History The term "solid-state" became popular at the beginning of the semiconductor era in the 1960s to distinguish this new technology based on the transistor, in which the electronic action of devices occurred in a solid state, from previous electronic equipment that used vacuum tubes, in which the electronic action occurred in a gaseous state. A semiconductor device works by controlling an electric current ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Buildings And Structures On The National Register Of Historic Places
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in Track (rail transport), tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on Railroad tie, sleepers (ties) set in track ballast, ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower friction, frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The rail transport operations, operation is carried out by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Buildings And Structures In Santa Ana, California
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electrical Substations
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a un ...

Ivy Substation (also known as the Ivy Park Substation or Culver Substation) is a 99-seat theatre in Culver City, California which formerly housed power equipment for the nearby electric railways and Ivy station. It was listed on the National Register of Historic Places in 1981. History A single story, rectangular shaped building in the Mission Revival style, it was built in 1907 as a traction substation by the Los Angeles Pacific Railway which subsequently became part of the Pacific Electric railway in 1911. Made of brick covered in stucco, the large interior once held old style rotary mechanical rectifiers to convert very high voltage alternating current (AC) to 600 volt direct current (DC) to operate run cars for serve nearby streetcar and interurban lines: the PE's Venice Short Line, Redondo Beach via Playa del Rey Line, and Santa Monica Air Line. It remained in service until 1953. The old equipment was removed and the building was purchased by the City of Los Angeles, ...
