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 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.
A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.
Layout of a spot low-voltage network In electricity distribution networks, spot network substations (network transformers) are used in interconnected distribution networks. They have the secondary network (also called a grid network) with all supply transformers bussed together on the secondary side at one location.
Substation: This is the part dealing with the different entities of a substation including various devices, interconnections and other functionalities. The elements include power transformers, Voltage Levels, bays, General Equipment, conducting equipment like breakers.
Electric power distribution is the final stage in the delivery of electricity. Electricity is carried from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 33 kV with the use of transformers . [ 1 ]
By protecting the line from lightning, the design of apparatus in substations is simplified due to lower stress on insulation. Shield wires on transmission lines may include optical fibers (optical ground wires/OPGW), used for communication and control of the power system. HVDC Fenno-Skan with ground wires used as electrode line
