Course Catalogue.

After participating in this course, you will be able to:

• Understand motor protection fundamentals
• Identify potential improvements to existing motor protection systems
• Know how to specify motor protection schemes for new equipment
• Calculate and apply settings for various protection elements
• Grasp the concepts discussed in IEEE Standard 242-2001, Recommended Practice for Protection and Coordination of Industrial and Commercial Power Systems and its relation to the motor protection approaches discussed in the applicable section of CEC-2012.

Description
This course covers a range of topics related to electrical motor protection in industrial settings. In addition to theoretical explanations, real-world examples of motor protection schemes are presented to give attendees knowledge that can be put into practice immediately.

Objective
To provide participants with a solid understanding of motor protection application concepts. Participants will leave the course with the tools and knowledge necessary to address motor protection projects in their own work environments.
