The basic principles of high voltage transformers, from a protection & control perspective.
Electromagnetism, Voltage & Current Transformation, Ratios and Polarity, Potential & Current Transformers, 3 Phase Transformers Construction, Transformer
Basic Electrical; Mathematics; Trigonometry
Electromagnetic forces interact with electrically charged particles and electromagnetic fields; this course will study how these forces lead to voltage & current transformation. Ratios and polarity is also studied leading to the introduction of potential transformers & current transformers, and their use in conjunction with the relevant instruments such as ammeters, voltmeters, watt meters and energy meters.
Transformer core construction along with losses & cooling mitigation techniques. 3 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 Connections: (Y – Y; Delta – Delta; Y – Delta; Delta – Y & Y – Zag Zig) are examined along with Transformer Clock System Vector Nomenclature.
Oil Analysis and the Buchholz Relay are also studied.
