Hi and welcome everyone to our course " Ultimate Electrical Transformers for Power Engineering"In this course, you are going to learn everything about electrical power transformers starting from the operation, theory, and design of three phase transformers moving to realizing the different types of transformers and their applications in the electric network, ending with a complete study on transformer protection, testing, and commissioning.Thus, this course is designed to take you from zero to hero concerning electric power transformer engineering field.The course is structured as follows:Firstly, a complete overview on the transformer theory and operation is illustrated through the following topics:Transformer theory of operation Ideal vs. Real transformersTransformer equivalent circuit (Exact and approximate)Phasor diagram of ideal and real transformersThen, the next topic will be about the assessment of transformer performance through the following topics:Transformer losses Hysteresis losses vs. Eddy current lossesTransformer efficiency Transformer regulationHow to perform open and short circuit tests to obtain transformer parametersThen, a complete study on three phase transformers is introduced since 99% of power transformers are actually three phase transformers. Thus, three phase transformers are explained in depth through the following topics:Construction, types, and connections of three phase transformersHow to get the per phase model of three phase transformers ?Per unit analysis in three phase transformersHow to get the per unit transformer parametersTransformer vector groupHow to obtain winding connections of any transformer vector group with examples ?Then, you are going to learn about the manufacturing and construction of power transformers explaining all the transformer parts. The following topics will be covered:Transformer core manufacturingCore type vs. Shell type transformersTransformer winding manufacturingHelical, Crossover, Disc, and Sandwich windingsTransformer main and conservator tankImportance of transformer oilBreather unit, Buchholz relay, Surge arrester, and Rod gap in power transformersTransformer terminals and bushingsTransformer cooling methodsThen, the next topic will be about the different factors that affect the transformer operation. These factors are discussed through the following points:Temperature rise and thermal ratingRelation between temperature rise and transformer loadingEffect of harmonics on transformersHarmonics mitigation and K-factor transformersInrush current in transformerOver fluxing and its effect on transformersReasons for humming noise coming from transformerEarthing of transformersThe next topic is about a complete study on different types of transformers and their applications in power systems. The following types of transformers are discussed in details:Power transformersDistribution transformersCurrent Transformers (CT)Voltage Transformers (VT or PT)Auto TransformersEarthing (grounding )transformerPhase shifting transformer (PST)Booster transformerThree winding transformer (tertiary winding)High voltage testing transformer (HVT)Then, we are going to a complete study on transformer protection where we are going to know identify the different transformer faults and provide a suitable protection device to this type of fault. The following outlines are discussed in depth:Types of transformer faultsProtection functions in transformerCore-balance leakage protectionCombined Leakage and phase fault ProtectionDifferential protection of transformersCT connections in transformer differential protectionHow to calculate CT ratios for differential protectionHarmonic restraint relayOver fluxing protection (Volt/Hertz relay)Restricted earth fault protectionOil and winding temperature trip relaysPressure relief device (PRD)Then, The next topic is about transformer testing, commissioning, and diagnostics where we are going to perform routine, type, and special test on power transformers to ensure the healthiness of the transformer before its energization on the site. The following tests are performed and explained:Insulation resistance (IR test)Tan Delta test (Dielectric loss test)Partial discharge (PD test)Hi-Pot test (Applied voltage test)Induced voltage testImpulse voltage testOil breakdown voltage (BDV) testDissolved gas analysis (DGA) TestTransformer turns ratio (TTR) testWinding resistance testMagnetizing current testPercentage impedance testVector group testFinally, Complete MATLAB Simulations on electrical transformers are done such as:MATLAB Simulation of 1-ph and 3-ph transformersPractical transformer Vs. Ideal transformer in MATLAB/SimulinkEfficiency, Losses and Voltage regulation calculations in MATLAB/SimulinkNo load and short circuit test of 1-ph and 3-ph transformers in MATLAB/SimulinkSo, if you are Looking for a COMPREHENSIVE course about Electric Power Transformer Engineering ? If your answer is YES, then you're definitely in the right place.
