Through my practical experience (19 years) in the field of electrical substations and working with various consulting offices in the design of medium voltage distribution networks for many important projects that require taking into account the accuracy in various electrical calculations, in addition to my obtaining a master’s degree in the engineering sciences in electrical power and machines engineering, entitled “Detection and Identification of Electrical Power Quality Problems using the advanced Artificial Intelligence Technique (LSTM). This course was prepared using the best engineering programs that link the academic/theoretical side with practical/reality in the High Voltage and Extra-High Voltage substations in addition to the Medium Voltage distribution networks.
This unique way of explanation and preparation of the course has been thought to suit all engineering and technical levels, starting from students of engineering universities and various technical institutes and even specialized engineers with high experience in the field of electrical power and distribution systems, especially the electrical contracting field, distribution networks and consulting offices.
This course was explained in a practical way based on the simple theoretical speech and attention to the practical explanation and reality pictures so that we can link the academic/theoretical study with what is actually present in the practical reality for the actual application after passing this course.
This course is closely related to electrical distribution systems and various contracting works. In this course, I offer the following:
* The meaning of Electrical Loads Calculations.
* The difference between dynamic or motors loads and static loads.
* The importance of the derating factors (D.F) in electrical loads calculations, and if we ignore these factors in our calculations, what will happen?
* In detail and step by step, I will explain, how to make the voltage drop (V.D) calculations for any cable.
* I will talk about, the short circuit (S.C) calculations for electrical power cables.
* I will explain how to choose the correct cross-section area (C.S.A) for the neutral cable and the earthing cable conductor.
* The difference between the Miniature C.B (MCB), Molded Case C.B (MCCB), and the Air C.B (ACB).
* In detail and step by step, how to make the correct and accurate calculations for any static load.
* I will give you an example of static load calculations and I will explain in detail and step by step, how to make the correct and accurate calculations for this load.
* I will explain how to know and calculate the starting current for any motor.
* I will explain in detail and step by step, how to make the correct and accurate calculations for any dynamic or motor loads.
* I will explain how to make correct calculations of the main cable and the main circuit breaker (C.B) for a group of individual motors or different loads.
* I will give you an example of dynamic or motor load calculations and I will explain in detail and step by step, how to make the correct and accurate calculations for these motors.
* I will give you a very important example of the office building calculations which consists of: the basement floor, ground floor, first floor, second floor, and roof floor with different loads of static loads and dynamic or motor loads like water pumps, chillers, and elevators.
* I will explain in detail and step by step:
– How to calculate the rated current of each circuit breaker (C.B) in ampere (A).
– How to calculate the cross-section area (C.S.A) of each cable in square-mm.
– How to calculate the rated current of the main circuit breaker (C.B) in ampere (A).
– How to calculate the cross-section area (C.S.A) of the main cable of each floor in square-mm.
* Finally, the last lecture is for the distribution transformer and the main distribution board calculations.
Who this course is for:
- Students of various engineering colleges and technical institutes – all engineers in consulting offices, electrical contracting projects, and distribution companies.
