About This Class

​Welcome to my own course in my series for power system explanations, in this course we are going to discuss the following topics related to electrical power substations:

  1. We will discuss function, classification and voltage of electrical substations.

  2. We will discuss its main components like power transformers, conductors, insulators, switch gears, current transformer, capacitor voltage transformer and voltage transformer.

  3. We will discuss the different types of circuit breakers, relays and their classification according to time, construction and function.

  4. We will discuss the difference between circuit breaker and fuse, in addition to their applications.

  5. We will understand the definition of IP or ingress protection.

  6. We will explain the grounding system including the effect of current on human body, components of grounding system, types of electric hazards and classification of earthing system.

  7. We will measure the earthing resistance by Megger and three point method.

  8. We will learn how to do an earthing system using Etap program.

  9. We will learn about the ring main unit and its importance in electrical power system.

  10. We will discuss the types of switches used in electrical power system and substations.

  11. We will discuss the overhead transmission lines, underground cables and difference between them.

  12. We will learn about busbars in power system, its importance, its different schemes and how to select them.

  13. We will understand the lightning arrester and wave trap which are used in substations.

  14. We will discuss the air and gas insulated substations.

  15. We will discuss how to design an electrical substation and single line diagram of 66/11 kV substation.

And much more,

See you in my own course .
