A course on Industrial and Substation Grounding & Bonding typically aims to provide a thorough understanding of the principles, practices, and standards involved in grounding and bonding for industrial facilities and substations. This course aims to equip professionals with the knowledge and skills necessary to design, implement, and maintain effective grounding and bonding systems in industrial and substation

 

Course Objectives:

1. Understand Grounding Principles: Gain knowledge of the fundamental principles of grounding and bonding, including why grounding is essential for safety and equipment protection

2. Learn Industry Standards and Codes: Familiarize with standards such as IEEE 80, IEEE 142, NFPA 70 (NEC), and other industry-specific regulations.

3. Design Grounding Systems: Develop skills in designing grounding systems for industrial facilities and substations, focusing on effective earth resistance, fault current paths, and lightning protection.

4. Evaluate Grounding Systems: Learn how to assess existing grounding systems for compliance, safety, and performance.

5. Implement Bonding Techniques: Understand the importance of bonding different parts of an electrical system to maintain equal potential and prevent dangerous step and touch voltages.

6. Use Ground Testing and Analysis Tools: Gain hands-on experience with ground testing equipment and simulation software to analyze grounding system performance.

7. Mitigate Grounding Risks: Learn techniques to mitigate common grounding issues like stray currents, electromagnetic interference (EMI), and ground potential rise (GPR).
