Overcurrent protection is a fundamental aspect of power system reliability and safety, ensuring that electrical networks can efficiently detect and isolate faults. This advanced course is designed for power system engineers, protection specialists, and technical professionals who are seeking to enhance their expertise in overcurrent protection systems, protection relays, and coordination.

What You’ll Learn:

The course begins with a solid foundation in overcurrent protection, introducing the basic principles and mechanisms used to detect and respond to excessive currents. Through a series of in-depth lectures, practical examples, and real-world case studies, you will explore the following critical topics:

  1. Introduction to Overcurrent Protection:

    • Understanding the role of overcurrent protection in safeguarding electrical systems.

    • Key concepts such as fault detection, isolation, and clearing in a timely manner to prevent equipment damage and ensure safety.

  2. Zones of Protection and Overlap:

    • Exploring the concept of protection zones to prevent unintended equipment tripping.

    • Understanding how overlapping protection zones create redundancy and enhance system reliability.

  3. Unit vs. Feeder Protection:

    • Differentiating between unit (transformer, generator) and feeder protection.

    • Understanding the applications and benefits of both types in modern power systems.

  4. Primary, Backup, and Duplicate Protection:

    • Defining the role of primary and backup protection schemes, and the need for duplicate protection to handle fault scenarios.

    • Ensuring continuity of protection in case of relay or system failure.

  5. Selectivity and Coordination:

    • Delving into the concept of selectivity, or discrimination, ensuring that only the faulty section of the network is isolated during faults.

    • Principles of coordination between protective devices to minimize system disruptions.

  6. Grading Time and Time Dial Settings:

    • How to calculate and apply time grading to coordinate relays at different levels.

    • Understanding time dial settings and how they influence relay operation times.

  7. Plug Settings and Plug Setting Multiplier (PSM):

    • Introduction to plug settings for adjusting the current at which relays operate.

    • Calculating and applying plug setting multipliers for effective protection coordination.

  8. Types of Protection Systems:

    • Exploring various types of protection, including instantaneous, inverse time, and definite time relays, and their respective applications in power systems.

  9. Relay Settings Case Study:

    • A hands-on case study simulating real-world relay settings and coordination for a typical electrical network.

    • Analyzing fault conditions and applying the knowledge gained to configure relays for optimal protection.

Learning Objectives:

By the end of this course, participants will:

  • Master the Fundamentals of overcurrent protection systems, gaining a clear understanding of their role in power system safety.

  • Develop Practical Skills for designing and configuring protection systems for various electrical installations, including feeders, transformers, and generators.

  • Apply Key Concepts such as selectivity, coordination, and grading in real-world scenarios to enhance system performance.

  • Perform Relay Coordination using time dial and plug setting adjustments to fine-tune the protection response.

  • Implement Effective Backup Strategies to ensure continuous protection even under relay failure conditions.

  • Work with Case Studies that provide hands-on experience in setting relay protection schemes for complex electrical systems.
