Description

Through my practical experience (22 years) in the field of electrical substations for medium voltage (MV), high voltage (HV), and extra-high voltage (EHV), as well as working with various consulting offices in designing electrical distribution networks for many important projects that require accuracy in various electrical calculations, in addition to obtaining a Master's degree in Engineering Sciences in Power and Electrical Machines Engineering titled "Detection and Identification of Power Quality Problems using advanced Artificial Intelligence techniques (LSTM)", this course and these very important questions were prepared using the best engineering programs that connect academic/theoretical aspects with practical/reality in high voltage and extra-high voltage electrical substations, as well as distribution networks for medium and low voltages.This unique approach to explanation and question preparation has been designed to cater to all engineering and technical levels, starting from students in engineering universities and various technical institutes, all the way to highly experienced specialized engineers in power systems and electrical distribution.The course has been explained in a practical manner, relying on simplicity in theoretical explanations and placing greater emphasis on visuals and real-life practical examples. This approach allows us to connect academic theoretical study with what actually exists in practical reality for real-world application after completing this course.The course we have is closely related to the power systems and electrical distribution systems. In this course, we provide the following:Advanced Concepts in Electrical Grounding and Fault Mitigation* A quick
