Modern Power System Protective Relaying Virtual

Course Overview:

This Modern Power System Protective Relaying training seminar has been designed to provide a clear and perfect understanding of power system protection schemes and devices including protection relays, fuses, circuit breakers, and other protective devices. In modern power systems, nowadays, protection systems play a significant role in efficiently running plant operations, utility switching, industry load transfer, maintenance programs, and investment policies.

The outcome is to minimize system outages and to keep the maintenance and repair costs at reasonable prices. With the advancement of technology, now there is a need for many system operators, electrical engineers (at all levels of proficiency), asset engineers, and project engineers to learn more about the power system protection concepts, logic, and applications to acceptable levels.

Course Objective:

By the end of this training, participants will be able to:

  • Develop and analyze typical power systems and their associated protection systems
  • Operational principles and types of electrical protection
  • Design of different types or relays
  • Protection coordination and architecture
  • Protection for feeders, motors and transformers
  • Select fit-for-the-purpose protection relays and other related devices
  • Develop design of protection schemes
  • Identify the motors faults and how to protect
  • Identify the motor nameplate and motor protection and control
