What you will learn

Electromagnetism, Voltage & Current Transformation, Ratios and Polarity, Potential & Current Transformers, 3 Phase Transformers Construction, Transformer Classifications, Losses & Cooling, Per Unit Equivalent Circuits, 3rd Harmonic Currents problems, Tertiary Windings, The Buchholz Relay, Oil Analysis, Transformer Connections: Y – Y, Delta - Delta, Y - Delta, Y - Zig-Zag, Transformer Over-Current Protection, Transformer Differential Protection, Relays old and new

Description

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.

Good course, I found the display of pictures, and knowledge of devices/legacy devices in use, a great help. I've also found he simplified a few concepts other presenters made complex.

The instructor is excellent . I would recommend all his courses as I have bought them all. He is so passionate and so responsive. He provides his students with in-depth knowledge and attempt to arm them with the best skills to master the power engineering profession. They are a few professionals like him who back their practical teachings with profound theoretical teachings. I am looking forward to his future courses and I hope he will produce tens of them .
