19 Components used in Electrical Substation

Electrical and Electronics Engineering feature image

The substation is an integrated network of different types of electrical types of equipment. This network helps to provide continuity of power from generating units to consumer ends.

There are multiple ways to install the substation (basically, in the form of indoor and outdoor types). For this installation, one should get familiar with all the basic requirements of the power substation.

In this article, I am listing the main electrical substation components for an overhead power system.

What are the basic requirement of electrical substation?

Keep scrolling the list of main parts of substation one by one,

  1. Overhead power lines
  2. Transformer
  3. Ground (earth) wire
  4. Circuit breaker
  5. Lightning arrester
  6. Fuse
  7. Busbar
  8. Isolating switches
  9. Battery
  10. Insulator
  11. Capacitor bank
  12. Relay (overcurrent and earth fault type)
  13. Instrument (current and potential types) transformer
  14. Distribution panel board
  15. Wave Trapper
  16. Switchyard
  17. Measuring and indicating instruments
  18. Outgoing feeder
  19. Security fencing

All these major types of equipment are assembled together to set up substations.

Each component has a specific role and function to control the voltage, to switch at fault condition and, to protect from hazard situation in the power system.

Also, we can include other electrical substation components as per the power requirements.
