About This CourseBeginner

This course will teach how electromagnetic forces interact with electrically charged particles and electromagnetic fields, forces that lead to voltage and current transformation. Ratios and polarity is also studied leading to the introduction of potential transformers and 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 and cooling mitigation techniques. 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.

Who this course is for:

  • Engineers; Technologists; Technicians; Electricians; Managers; Supervisors; Superintendents; Electrical Students
