| dc.description.abstract | At present, the demand for electrical power is growing rapidly, and this can be fulfilled by
the power generating substations. There are different types of power generating substations
like thermal, atomic, and hydro-electric. Based on the availability of different resources,
substations are building at different locations, but these locations may not be closer to load
centers. The actual power utilization can be done by the load center. So it is essential to
transmit the power from the substation to load center locations. So, high and long
transmission networks are required for this function.
Power is generated fairly in the level of low voltage level; however, it is inexpensive to
supply the power at a high-voltage level. For preserving high and low voltage levels a
number of switching as well as transformation stations have to be produced among the
generating place & customer ends. Generally, these two stations are named as electrical
substations.
A substation is an electrical system with high-voltage capacity and can be used to control
the apparatus, generators, electrical circuits, etc. The Substations are mainly used to convert
AC (alternating current) to DC (direct current). Some types of substations are tiny in size
with an inbuilt transformer as well as related switches. Other types of substations are very
huge with different types of transformers, equipment, circuit breakers, and switches.
The different types of substations mainly include Step-up Type Substation, Step-down
Transformer, Distribution, Underground Distribution, Switch yard, Customer Substation,
and System Station | en_US |
