In today’s modern day and age, no one can even conceive of fulfilling any task without electricity being available. Electricity is required for everything, from keeping the water cold and the food fresh in the refrigerators to the air conditioning that is required in the summer months when the temperature gets extremely high and unbearable. Also, in the months of winter electricity is required for heating purposes.
In such a scenario, the job of those who are producing and distributing electricity becomes very vital. It is the job of the Distribution Substation to send the electricity in the right amount and the right voltage to the final consumers.
After electricity has been produced in the generating station, from there the produced electricity travels to the distribution substation where the voltage is transformed from low to high or vice-versa. Between the electricity being produced in the generating station and reaching the final consumers or the users, the electric current may flow through a number of distribution substations at different voltage levels.
A distribution substation contains transformers in order to transform voltage. Generally, a distribution substation has two kinds of transformers- a step- up transformer and the other one is the step- down transformer. As the name suggests, the step-up transformer function is to increase voltage and reduce the electric current. On the other hand, the job of the step- down transformer is to decrease the voltage and increase the electric current.
The role that the Distribution Substation plays is extremely important. They transfer the electric current from a transmission system into a distribution system. In a Distribution Substation generally there are two transmission lines that provide the input and it also contains a set of feeders that act as output. The voltage runs through the substation, and out of the feeders. It then travels to a distribution transformer and generates electricity.
