Training on Electric Power System Protection

Relays, Protection Schemes & Fault Analysis for Power Engineers

Electric Power System Protection is a critical function in power generation, transmission, and distribution networks. Any failure in protection systems can lead to equipment damage, large-scale blackouts, safety hazards, and financial losses.

This training program is designed to provide practical, field-oriented knowledge of power system protection, focusing on protective relays, fault detection, coordination, and real-time protection practices used in substations and industrial power systems.

Why Power System Protection Training Is Essential

Many Electrical Engineers face challenges such as:

  • Strong academic knowledge but limited practical exposure to protection systems

  • Difficulty understanding relay settings, coordination, and fault behavior

  • Lack of hands-on understanding of substation protection schemes

  • Inability to troubleshoot protection-related tripping issues

  • Requirement of protection knowledge for roles in utilities, EPC projects, and industries

This course is designed to close the gap between theory and real-world protection practice.
