Why Choose this Training Course?

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 Protection Relay Application training course is interactive and encourages delegates to participate through questions and answers. Case studies help further in better understanding the discussed topics.

The Protection Relay Application training 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

What are the Goals?

  • 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 transformers in correct operation of protection
  • Understand Circuit Breaker operation and maintenance requirements
  • Understand LV Motor starts and associated issues
