COURSE OVERVIEW:

Protective relaying is the critical "intelligence" that ensures the safety of equipment and personnel during abnormal system conditions. This course provides a technical framework for the design, setting, and coordination of modern numerical relays within high-voltage environments. Participants will explore the mechanics of "Digital Protection," moving from simple overcurrent logic to sophisticated differential and distance schemes that utilize fiber-optic communication.

The scope of this training addresses the full spectrum of protection zones, including generators, transformers, busbars, and transmission lines. It covers the technical nuances of the IEC 61850 protocol, focusing on the transition from hardwired logic to "GOOSE" messaging and "Process Bus" architectures. The curriculum provides a detailed focus on the interpretation of "Digital Fault Records" (DFR) to verify the correct operation of protection strings.

Coverage includes the implementation of advanced protection strategies such as "Adaptive Relaying" and "Wide Area Protection" (WAP). Attendees will learn to utilize simulation tools for protection coordination, determine "Reach" and "Time-Delay" settings, and troubleshoot "Hidden Failures" in secondary circuits. By combining protection theory with practical numerical relay configuration, the course equips professionals with the expertise required to ensure selective, fast, and reliable system isolation.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Define the fundamental principles of protection: Selectivity, Speed, and Reliability.
• Differentiate between "Electromechanical," "Static," and "Numerical" relays.
• Configure "Time-Overcurrent" (50/51) and "Directional" (67) protection.
• Design and set "Transformer Differential" (87T) and "Restricted Earth Fault" (REF).
• Implement "Distance Protection" (21) for transmission lines with Mho and Quad characteristics.
• Interpret and utilize the IEC 61850 standard for substation automation.
• Execute "Protection Coordination" studies to minimize system downtime.
• Analyze "Fault Waveforms" (COMTRADE files) to verify relay performance.
• Manage "Breaker Failure" (50BF) and "Busbar Protection" (87B) logic.
• Configure "Communication-Aided" schemes: POTT, PUTT, and Blocking.
• Verify the integrity of CT and VT circuits for protection accuracy.
• Conduct "Secondary Injection" testing on multi-function numerical relays.

TARGET AUDIENCE:

This course is intended for Protection Engineers, Substation Commissioning Engineers, Asset Managers, and Senior Electrical Technicians.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximize the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
