TRAINING.

Overview

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

• Identify and prevent safety hazards to personnel who come in contact with electrical systems
• Prevent equipment failures and malfunctions by employing proper grounding techniques
• Interpret codes and standards related to grounding
• Ensure proper operation of communication, computer and control systems by appropriate grounding and bonding
• Apply to your projects lightning protection methods

Description
Grounding and bonding systems ensure that electrical systems are safe from electric shock and fires by limiting the voltage imposed by lightning, line surges, or unintentional contact with high voltage lines as well as a ground fault. An integrated theory and practice approach will ensure you have a firm foundation of knowledge when you begin your next design or construction project or when you encounter problems in your electrical system which must be corrected for safety, operational or power quality reasons.

Case studies will be presented to discuss grounding and bonding applications in various areas (industrial and substation) to reinforce fundamental grounding principles common to a variety of applications.

Course Outline:

• Grounding
