Electrical substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions.
Between the generating station and consumer, electric power may flow through several substations at different voltage levels.
A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two different transmission voltages. They are a common component of the infrastructure.
Main equipments in distribution substations:
1. Distribution Transformer
2. Circuit breaker
3. Lightning Arrester
4. Air Break (AB) switches /lsolator
5. Insulator
6. Busbar
7. Capacitor Bank
8. Earthing
9. Fencing
10. Distribution panel board
