The high efficiency and reliability of power transformers have contributed to the domination of power networks since the beginning of the last century. Transformers play also a key role in the interconnection of power systems at different voltage levels. Without transformers, it would simply not be possible to use electric power in many of the ways it is used today. Consequently, transformers occupy prominent positions in the electric power system, being the vital links between power generating stations and points of electric power utilization.
This course is designed to provide delegates a detailed and up-to-date overview of transformer operation, maintenance, diagnosis, testing and lifetime extention. It covers the power transformer fundamentals including the main electric parameters and laws, magnetism and electromagnetism, Lenz and Faradays Laws, circuits, star and delta connections, theory, the role of transformers in power systems, standards, regulations and voltages as well as the various types and construction of transformers.
Further, the course will also discuss the special transformers, transformer components, materials, cooling of transformers, transformer performance, electrical parameters and transformer faults; the power transformer failure and faults; the proper power transformer protection, operation and factory acceptance test (FAT); the transformer installation, testing and commissioning; and the transformer maintenance, routine inspections, diagnostic analysis, life expectancy and extension.
During this interactive course, participants will learn the methods of insulating system and lifetime extension in transformer diagnostic; the insulation system composition, transformer oil types, thermal effects and energy losses; the heat transformer modes, insulation systems oxidation and degradation, corrosive sulphur effect and insulation system aging factors; the aging measurement, electrical diagnosis of insulation system, gas diagnostic analysis and chemical diagnostic analysis; and the physical diagnostics analysis, estimation diagnostic analysis, transformer lifetime extension and remaining life assessment (RLA).
