Introduction:

Protection relays are a vital component of modern power systems, ensuring the safe and selective isolation of faults to protect critical assets like feeders, busbars, and generators. Understanding their logic, configuration, and fault response behavior is essential for electrical engineers working in substations, utilities, and power plants.

This 5-day training program, designed by Global Horizon Training Center, provides participants with comprehensive in-classroom knowledge of protection relay operation, settings, and analysis. The program replaces hands-on field work with high-quality presentations, case study discussions, software screen recordings, and video demonstrations. This method ensures that even without lab access, participants gain practical insight into configuring relays, analyzing COMTRADE files, and troubleshooting faults effectively.

Objectives:

By the end of this training, participants will:

• Understand detailed protection principles for feeders, busbars, and generators

• Recognize the logic and architecture of numerical protection relays
