Need of 132 kV / 33 kV Substation

Question- State the need of 132 kV / 33 (EHV) kV Substation

1. 132 kV / 33 kV Substation is a type of transmission substation primarily installed to reduce the transmission losses. It receives electrical power from generating station via transmission line and delivers it to 33 kV consumers through suitable feeders.

2. It is used to control the electric power on various routes of the power system. It is used for switching purpose.

3. It helps to change some electrical characteristics such as voltage, power factor and frequency of electric supply in the transmission and distribution network.

4. 132 kV /33 kV Substation is located in primary transmission system at which 132 kV voltages is stepped down to 33 kV. Its main purpose is to reduce the transmission losses at different routes of the power systems and to perform

different switching operations.

5. To satisfy the load demand

6. To accommodate new power generation

7. To maintain the reliability of the power system

8. To step down AC voltage using transformer

9. To perform various switching operations

10. To interconnect the two different transmission voltages
