Hi and welcome everyone to our course "Ultimate Electrical Power System Engineering Masterclass"In this course, you are going to learn everything about power system analysis starting from the power system basics and fundamentals of single phase and three phase electric systems moving to designing and modelling different power system components such as: generators, transformers, and transmission lines, ending with a complete power system studies such as load flow studies and power system faults analysis. Thus, this course will be your complete guide in one of the main areas of power engineering: ( power system analysis )The course is structured as follows:Firstly, an overview on the power system structure is illustrated through the following topics:Generation, transmission, distribution, and consumption of electric powerHow to draw a single line diagram (SLD) of any power systemThen, the next topic will be about a review on basic electrical engineering concepts to be a quick refresh for you. The following topics will be covered:Different types of powers in power systemComplex power, power triangle, and power factor definitionspower factor correction Complex power flow in any power systemThen, a complete study of three phase systems is introduced since 99% of practical electric networks are actually three phase systems. Thus, three phase circuits are explained in depth through the following topics:Why we need three phase systems?Three phase supply and load Different 3-ph connections (star-star), (star-delta), (delta-star), (delta-delta) Difference between

This course aims to familiarize the learner with the interpretation of statistical measures and methods used in medical publications. It covers topics ranging from simple descriptive characteristics like mean and median to EBM indicators, statistical tests, especially tests of proportion significance, and statistical models (linear and logistic). Each lesson provides practical examples of using these measures and tools in published medical articles.What will you learn?This course aims to familiarize the learner with the interpretation of statistical measures and methods used in medical publications.
