The IEEE 693: Recommended Practice for Seismic Design of Substations. [ 1 ] is a Institute of Electrical and Electronics Engineers standard. This standard is recognized also by American National Standards Institute , and is used mainly in the American Continent.
Substation integration refers to combining data from the IED's local to a substation so that there is a single point of contact in the substation for all of the I&C data. Power-system automation processes rely on data acquisition; power-system supervision and power-system control all working together in a coordinated automatic fashion.
Hydro-Québec's Lévis substation where the de-icer is located. The Levis De-Icer is a High voltage direct current (HVDC) system, aimed at de-icing multiple AC power lines in Quebec, Canada. It is the only HVDC system not used for power transmission. In the winter of 1998, Québec's power lines were toppled by icing, sometimes up to 75 mm. To ...
The first step in planning a substation layout is the preparation of a one-line diagram, which shows in simplified form the switching and protection arrangement required, as well as the incoming supply lines and outgoing feeders or transmission lines. It is a usual practice by many electrical utilities to prepare one-line diagrams with ...
The National Electrical Safety Code (NESC) or ANSI Standard C2 is a United States standard of the safe installation, operation, and maintenance of electric power and communication utility systems including power substations, power and communication overhead lines, and power and communication underground lines.

The two major and three minor NERC interconnections, and the nine NERC Regional Reliability Councils. 735 kV substation near the Robert-Bourassa generating station. Hydro-Québec's electricity transmission system (also known as the Quebec interconnection) is an international electric power transmission system centred in Quebec, Canada.
Current transformers, especially those intended for high voltage substation service, may have multiple taps on their secondary windings, providing several ratios in the same device. This can be done to allow for reduced inventory of spare units, or to allow for load growth in an installation.
