Q & A in the Fundamentals of Electrical Power Systems

Through my 20 years of practical experience in electrical substations for medium (MV), high (HV), and extra-high voltage (EHV), and working with various consulting offices in designing electrical distribution networks at medium voltages for numerous projects, along with obtaining a Master of Science degree in Power and Electrical Machines Engineering with the thesis titled 'Detection and Identification of Power Quality Problems using advanced Artificial Intelligence techniques (LSTM)', this course and these very important questions have been prepared using the best engineering programs that connect theoretical academic knowledge with practical reality in high and extra-high voltage transformer stations, as well as medium and low voltage distribution networks. This unique approach to teaching and the important questions have been designed to cater to all engineering and technical levels, starting from university students in engineering and various technical institutes to specialized engineers with extensive experience in power and distribution systems. The course presents practical questions and answers, focusing on simple theoretical concepts while placing greater emphasis on images and explanations from real-life applications.

This way, we can link theoretical academic study with what exists in practical applications after completing this course. Our course is closely related to electrical power systems and electrical distribution systems, and in this course, we present ideal answers to the following questions:(1) What is the difference between alternating current (AC) and direct current (DC). (2) What are the components of the electrical power system.

(3) What is the main source of voltage (V), current (I), and frequency (F) in the electrical power system. (4) What is the meaning of resistance (R). Give examples and explain the type of current passing through it.

(5) What is the meaning of inductive reactance (X_L). Give examples and explain the type of current passing through it. (6) What is the meaning of capacitive reactance (X_C).
