  Electric Power eTool: Illustrated Glossary: Substations
Substation Types: Although, there are generally four types of substations there are substations that are a combination of two or more types.
A step-up transmission substation receives electric power from a nearby generating facility and uses a large power transformer to increase the voltage for transmission to distant locations.
A substation can have circuit breakers that are used to switch generation and transmission circuits in and out of service as needed or for emergencies requiring shut-down of power to a circuit or redirection of power.

 PEABODY WESTERN COAL COMPANY -- June 12, 2003
Substations have to be relocated from time to time as the pit expands.
All other substations that he is familiar with are wired so that the electricity flows through the circuit breakers before entering the knife blade switches.
He did not know that the substation was wired differently and the fact that Hancock testified that it was "bad electrical practice" to rely on the circuit breakers to de-energize the circuit is "not sufficient to sustain a finding of unwarrantable failure conduct." (P. Br.

 Substation-Design
The reason that such a layout is known as a 1 1/2 circuit breaker is due to the fact that in the design, there are 9 circuit breakers that are used to protect the 6 feeders.
Substation layout consists essentially in arranging a number of switchgear components in an ordered pattern governed by their function and rules of spatial separation.
The choice is influenced by the height of towers and the proximity to the substation.

One of the largest electric substations along the "Balloon Route" rail line from downtown Los Angeles to the Pacific Ocean, construction of the Ivy Park Substation was one of a number of improvements made possible by the acquisition of a 51% interest in the company by Southern Pacific in early 1906.
The Substation is believed to be the only remaining major structure built by the Los Angeles Pacific Company to survive with a substantially unaltered exterior, and one of the least-altered electric railway substation buildings to survive in Southern California.

 Substation Switches Overview
Typical applications for SEECO substation switches include high side disconnects, isolating and by-passing breakers, bus sectionalizing, and isolating arrestors, metering equipment, and other apparatus.
The design of the jaw (female) contacts is very forgiving, allowing a substantial amount of structure movement and deflection without diminishing contact pressure or effectiveness of current transfer.
Substation switches can also be supplied with other complementary SEECO products, including motor operators, pre-assembled trusses, vacuum interrupters, ground switches, and externally mounted auxiliary contacts.

 Power distribution substation patent invention
A unit substation is a power distribution substation, which generally receives electrical power at a higher voltage, and distributes power to a network at a lower voltage, such as, for example, in a network used in a hospital or other facility.
A unit substation typically consists of three physically and electrically connected components, comprising a primary protective or isolation device, a substation transformer, and secondary distribution equipment.
For example, in the traditional distribution substation, the primary protective device is physically separated from the secondary distribution equipment by the substation transformer.

In that time we have supplied some 5,500 air insulated and gas insulated substations for all voltage levels and all climates, from the densest downtown locations to the harshest environments on earth.
In those days, substations were equipped with oil boiler circuit breakers rated at 8 kV, to be able to switch 8 kV in 1891 was a major sensation.
There are two types of substation: transmission substations with voltage ratings from 170 kV to 800 kV, and distribution substations which step down the voltage from 170 kV to the medium voltage level required by the customer.

To size the data warehouse, the utility must determine who the users of the substation automation system data are, the nature of their application, the type of data needed, how often the data is needed, and the frequency of update required for each user.
In existing substations, there are several alternative approaches, depending on whether or not the substation has a conventional RTU installed.
This approach is applied most frequently to substation transformers and high voltage electric supply circuit breakers to minimize the maintenance costs of these devices, as well as to improve their availability and extend their useful life.

Substations represent an intricate interconnected collection of devices that serve as electromagnetic wave emitters and receptors.
Because outside contractors/consultants execute most audits, substation asset owners need to be very clear as to what needs to be measured, where measurements will take place, and how the results will be analyzed.
The audit program will be presented in technical report form, and through a suite of technical transfer courses designed to provide substation designers and substation maintenance engineers the tools for ensuring reliable application of the technologies of the future to new and existing substations.

The property owners argued the presence of the substation would ruin the quality of life and cause their property values to plummet.
Her husband, William Pratt, argued before the County Commission that traditionally substations have not been built within a mile of residential areas in rural Utah and that there are better locations available.
He argued that the 12-foot drop in the substation was unnecessary, and if the county required it, the excavation work would add to the cost that the county should have to pay.
