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:
- We will discuss the function, classification, and voltage of electrical substations.
- We will discuss its main components like power transformers, conductors, insulators, switch gears, current transformers, capacitor voltage transformers, and voltage transformers.
- We will discuss the different types of circuit breakers, relays, and their classification according to time, construction and function.
- We will discuss the difference between circuit breakers and fuse, in addition to their applications.
- We will understand the definition of IP or ingress protection.
- We will explain the grounding system including the effect
of current on the human body, components of the grounding system, types of
electric hazards, and classification of earthing system.
- We will measure the earthing resistance by Megger and the three-point method.
- We will learn how to do an earthing system using the Etap program.
- We will learn about the ring main unit and its importance in electrical power systems.
- We will discuss the types of switches used in electrical power systems and substations.
- We will discuss the overhead transmission lines, underground cables, and the differences between them.
- We will learn about power system busbars, their importance, their different schemes, and how to select them.
- We will understand the lightning arrester and wave trap which are used in substations.
- We will discuss the air and gas-insulated substations.
- We will discuss designing an electrical substation and a single-line diagram of a 66/11 kV substation.
