Electricity leaving the town passes through a substation to step-up the voltage again so it can be efficiently transmitted to the next set of consumers. The substation also has provisions for bypass, so if electricity is being transmitted to a set of towns, one small another very large, not all electricity entering the small town substation will be stepped-down, some will bypass the substation and carryon to the large town substation, this is especially the case if the distance between the two towns is large.
A typical mid network substation is shown below, with the blue line being the bypass line and the red lines, being the step-up or down line s. Components of the substation above are: 3. Primary and secondary power lines 1 and 12 respectively 2. Ground wire 3. Transmission lines 4. Transformer used to measure primary line voltage 5. Disconnect switches 6.

Electricity is most often generated at apower plant by electromechanical generators, primarily driven byheat engines fueled by combustion or nuclear fission but also byother means such as the kinetic energy of flowing water andwind. Other energy sources include solar photovoltaics andgeothermal power. Kelley Koerstein Pundit.
What are the types of substation? Flaminio Vigiola Pundit. How many types of substation are there? Substation Types: Although, there are generally four typesof substations there are substations that are a combination of twoor more types. Step-up Transmission Substation. Step-down Transmission Substation. Distribution Substation. Underground Distribution Substation. Substation Functions.
Substation Equipment. Marcu Abalde Pundit. What are the components of substation? Elements of a Substation. Primary power lines. Ground wire. Overhead lines. Transformer for measurement of electric voltage.
Disconnect switch. Circuit breaker. Current transformer. Lightning arrester. Peli Gollasch Teacher. What is substation and its types? Classification of Substations. The substation is the medium of transferring the power fromgenerating unit to the consumer end.
The generation, transmissionand distribution are the main work of the substation. The substation which generates the power is known as thegenerating substation. Queren Zinin Supporter. What is HT and LT panel? A switch yard connects one part of power system to another without changing the voltage level while a substation have a Transformer to change the voltage Level it have almost all the equipment same as switch yards.
A switchyard is where the power is maintained at same level without change of voltage after generating transformer the power is feed to the switchyard with the help of conductor bar. Substation is the part of the power system where voltage level is changed and switching is being done. Moreover, Switch yard is the area where switching is being done and it is the intermediate substation between generation and distribution.
