This course covers the theoretical and practical operation of common electrical equipment and components, as well as provides participants with the necessary knowledge and skills to perform electrical maintenance and troubleshooting.
Participants will gain an understanding of the relationship between voltage and current to work on and troubleshoot electrical systems. The course will also cover Direct Current (DC) and Alternating Current (AC) circuit concepts, transformers' types of uses and their interaction in an electrical circuit, as well as the necessary knowledge to work on and fix motor control circuits.
As electrical hazards can result in serious injury to personnel that work on or around electrical equipment, the course will also focus on international safety requirements, including OSHA standards, and best practices. Participants will learn the steps needed for the prevention of electrical injuries.
Course Methodology
This course will be highly interactive and include group discussions, case studies and syndicate work. It will include practical exercises that will allow all participants to use the knowledge they gained to demonstrate their skills in troubleshooting electrical problems, and apply it to their work scenarios.
Course Objectives
By the end of the course, participants will be able to:
Apply tools and techniques to perform electrical maintenance and troubleshooting on various types of electrical equipment
Demonstrate a basic current, voltage and resistance relationships in electrical systems
Describe how inductors and capacitors work and interact with electrical circuits
Explain the theory of a generator and how a sine wave is produced
State the difference between a power and a distribution transformer and explain the cooling methods used for transformers
Minimize risks by identifying the hazards associated with electrical energy and by complying with safety guidelines
Describe and apply the requirements in EN 500110, the most widely used standard for the protection of individuals from the effects of electrical hazard
Target Audience
