Fundamentals of Three-Phase Electrical Transformers

Description

This course will teach you the fundamentals of electrical transformers in terms of electromagnetism, voltage and current transformation, ratios, and polarity, potential and current transformers, 3-phase transformer construction, transformer classifications, losses, and cooling, per unit, etc.

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 also studied leading to the introduction of potential transformers & current transformers, and their use in conjunction with the relevant instruments such as ammeters, voltmeters, wattmeters, and energy meters.

Overcurrent and restraint differential transformer protection is explained in detail, along with a look at some examples of “Old School relays” as well as modern IEDs (intelligent Electrical Devices).

Transformer Connections: (Y–Y; Delta-Delta; Y-Delta; Delta-Y and Y-Zag Zig) are examined along with Transformer Clock System Vector Nomenclature. Oil Analysis and the Buchholz Relay are also studied.
