Protection Relay Application Training Course

Introduction

Protection systems are installed in power system to prevent damages of electrical equipment by faults, to isolate a faulty part, and to maintain continuity of supply elsewhere in the system. Modern protection includes multiple protection functions as well as monitoring and recording features, self-diagnostics and analogue and digital data. Although the primary role of protective relays is to perform protection functions, relays also provide additional data and some control functions. The course is interactive and encourages delegates to participate through questions and answers. Case studies help further in better understanding the discussed topics.

The course will cover the following:

  • Power System Fault Analysis
  • Current and Voltage transformers
  • Protection Concept
  • Over Current and Earth Fault Protection
  • Pilot Wire and Distance Protection
  • Transformer Protection
  • HV Circuit Breakers principle of operation and maintenance
  • Principles of LV motor starts protection and maintenance

Objectives

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

    • Understand various electrical faults and their effects on the system
    • Learn how to calculate faults
    • Understand the purpose of protection systems and their basic operation
    • Identify types of protection, required for different applications
    • Appreciate the impact of current and voltage transformers incorrect operation of protection
    • Understand Circuit Breaker operation and maintenance requirements
    • Understand LV Motor starts and associated issues

Training Methodology

This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies, and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations. The online course is conducted online using MS-Teams/ClickMeeting.
