An Intensive 5-Day Training Course

Modern Power System Protective Relaying

  • Format: Classroom
  • Duration: 5 days
  • Language: English



This EuroMaTech training course of Modern Power System Protective Relaying has been designed to provide a clear and perfect understanding of modern 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.


At the end of this EUROMATECH Modern Power System Protective Relaying training course, delegates 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
  • Power Generation Electrical engineers
  • Electrical Maintenance Engineer
  • Electrical Technicians
  • Electrical Operators

This EUROMATECH Modern Power System Protective Relaying training course is based on adult learning concept. The facilitator will give plenty of input and then help participants to make sense of the themes through discussion and practice. It incorporates short inspiring demonstrations, roles play and practice to enhance learning. There will be ample time for Q&A, discussions with ‘return to work’ action planning. The program will reinforce key concepts within an inspiring and engaging learning environment. Pre & Post course assessments will be used to measure the effectiveness of this training and measure the skill and ability of participants.


This Modern Power System Protective Relaying training course will expose the various topologies to the delegates. Upon completion of the course delegates will able to understand, identify the required protection schemes and to select the proper protection component, and will be able to carry out coordination studies for their existing electrical equipment.
