In Electrical 3-Phase Power Transformers Fundamentals (Video on Demand), you'll learn ...
∙ The basic principles of high voltage transformers from a protection and control perspective
∙ Transformer Connections: (Y – Y; Delta - Delta; Y - Delta; Delta - Y and Y - Zag Zig) and Transformer Clock System Vector Nomenclature
Transformer core construction and losses & cooling mitigation techniques
Electromagnetic forces interact with electrically charged particles and electromagnetic fields. This course will study how these forces lead to voltage and current transformation. Ratios and polarity are explained, leading to the introduction of potential transformers and current transformers, as well as their use in conjunction with the relevant instruments such as ammeters, voltmeters, watt meters and energy meters.
Three-phase transformer configurations are studied, along with harmonic distortion, CT saturation and on-load tap-changer problems, and how these problems are dealt with. Over-current and restraint differential transformer protection is developed along with a look at some examples of " Old School relays" as well as modern IDE (intelligent Electrical Devices) relays, transformer clock system vector nomenclature, oil analysis, and the Buchholz relay.
