For anyone involved in the electrical power industry, a thorough understanding of transformers is paramount. The “Mastering Electrical Transformer Fundamentals Part 4” course on Udemy, led by an instructor with over 21 years of hands-on experience in operation, maintenance, and project management across various high-voltage installations, offers an invaluable continuation of this critical knowledge base.
This installment delves into the nitty-gritty of transformer construction and operation, exploring key components and phenomena that are crucial for safe and efficient functioning. The course meticulously covers the 85 parts of a transformer, providing a comprehensive overview of its intricate design. A significant portion is dedicated to understanding the vital role of oil in power transformers, including why it’s used and how to perform polarity tests, a fundamental aspect of transformer verification.
We get an in-depth look at the main and conservator tanks, sealed versus hermetically sealed designs, and the indispensable silica gel and breather system. The function of radiators, the direction of oil flow within them, and even the interpretation of radiator thermographic images are explained. The course also addresses the critical topic of transformer cooling, clarifying why dual ratings are provided on the nameplate and identifying the factors that dictate maximum loading capacity and influence transformer aging.
Furthermore, the course tackles the impact of temperature on paper aging and the inherent risks associated with overheating wet transformers. Understanding the ‘soak test’ and its purpose, as well as the common humming sound in transformers attributed to magnetostriction, adds another layer of practical knowledge. The detailed exploration of the Buchholz relay, from its installation and working principle to functional checks, NO contacts, bleeding, and internal views, is particularly noteworthy. The inclusion of sudden oil pressure relays, oil and winding temperature indicators, oil level indicators, and pressure relief devices highlights the comprehensive safety and monitoring mechanisms within a transformer.
Finally, the course addresses the crucial role of transformer bushings, the detrimental effect of moisture, and essential periodic checks and maintenance procedures. The instructor’s extensive background with organizations like Siemens Saudi Arabia and involvement in numerous high-voltage substation projects across Pakistan and Saudi Arabia lends immense credibility to the content. This course is highly recommended for electrical engineers, technicians, and anyone seeking to deepen their practical understanding of power transformers.
