Three Phase Power Transformer Fundamentals

Learn about Three Phase Power Transformer, Ideal and Real Transformer, Current and Voltage Transformers, Transformer Vector Group and Clock system, Transformer Construction and Cooling, Transformer Protections and Relays and much more.

05:40 Hours of Video Tutorial with total 10 Lectures with Quiz

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.

Covered is transformer core construction along with losses and 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. 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.

Upon completion of this course, participants will be familiar with:

 

  • Introduction to Three Phase Power Transformers
  • The Ideal Transformer
  • The Real Transformer
  • Instrument Transformers
  • Three-Phase Power Transformers
  • Transformer Clock System Vector Nomenclature
