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 transformer, capacitor voltage transformer, and voltage transformer.
-
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 breaker 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 electrical hazards and classification of earthing system.
-
We will measure the earthing resistance by Megger and 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 the electrical power system.
-
We will discuss the types of switches used in the electrical power system and substations.
-
We will discuss the overhead transmission lines, underground cables, and the difference between them.
-
We will learn about busbars in the power system, Its importance, Its different schemes and how to select them.
-
We will understand the lightning arrester and wave trap which are used in substations.
