Requirements
There are no requirements for this course, this course was designed to explain electricity and electrical systems in such a way that someone who does not have any electrical work experience will understand it. This course is not math intensive, but we will cover a few basic formulas. If mathematics is not your strong point, there is no shortage of online calculators that can do the calculations for you.
Description
This course was written in such a way that someone who does not have any electrical work experience will understand it. However, most people can learn something from this course even if they have previous electrical work experience or knowledge. It takes roughly one day to work through this course.By the end of this course, we will have a fair understanding of; 1. Electrical Circuit Basics. Voltage Current Resistance Power Energy Direct Current Alternating Current Series Parallel Ohm’s Law with examples Protective Systems 2. Single and Three-Phase Electricity. Single and Three-Phase power generation Single and Three-Phase transmission Single and Three-Phase circuit layouts 3. Electrical Transformers. Step-up Transformers Step-Down Transformers Single-Phase Transformers Three-Phase Transformers 4. Electrical Test Equipment and how to use them. Multimeters Clamp meters Insulation Resistance Testers PSC / Loop Testers Phase Rotation Testers ELCB / Polarity Testers Earth Resistance Testers 5. Single and Three-Phase motors.Single and Three-Phase motor control circuits Wye/Star and Delta configurations Star-Delta startersSingle and Three-phase motor inspections. (External and internal)Fault Finding.Just like this course description, the videos are short, on topic and straight to the point. This course does not qualify you as an electrician and does not authorize you to conduct any electrical work. This course is not math intensive, but we will cover a few basic formulas. If mathematics is not your strong point, there is no shortage of online calculators that can do the calculations for you..
