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.
Learning Objectives
Upon completion of this course, participants will be able to:
- Explain the principles of electromagnetism relevant to transformers.
- Describe voltage and current transformation in a transformer.
- Interpret transformer ratios and polarity.
- Distinguish potential transformers from current transformers.
- Describe three-phase transformer construction.
Video on Demand
This course is a recorded version of a live lecture and will be streamed directly to your computer's media player. Our format is generally compatible with media players included with all computers and mobile devices. After watching the video presentation, you will return to your account to take the online quiz. While this is a recording of a live presentation, please note that this recording will not qualify as a "live" or "interactive" continuing education activity in those jurisdictions where it is required.
Certificate of Completion
You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 24 questions. PDH credits are not awarded until the course is completed and quiz is passed.
