COURSE OVERVIEW:

The transition from a dormant relay to an active guardian of the power system requires a rigorous commissioning and maintenance regime. This course provides a technical framework for "Protective Relay Management," focusing on the lifecycle of a relay from initial installation to troubleshooting field failures. Participants will explore the mechanics of "Secondary Injection," learning how to use advanced test sets to validate the complex algorithms of numerical, static, and electromechanical relays.

The scope of this training addresses the practical aspects of commissioning within a substation environment, focusing on the verification of "Tripping Logic" and "Inter-relay Communications." It covers the technical nuances of "Fault Simulation," focusing on the use of modern software to generate transient waveforms that challenge relay stability and speed. The curriculum provides a detailed focus on "Troubleshooting," ensuring that participants can distinguish between "Internal Relay Faults," "Wiring Errors," and "Sensor Failures" that lead to incorrect protection operations.

Coverage includes the implementation of "Periodic Maintenance" programs that comply with international reliability standards. Attendees will learn to interpret "Self-Diagnostic" codes, manage "Firmware Upgrades," and perform "Post-Fault Investigations." By combining hands-on testing techniques with logical diagnostic workflows, the course equips professionals with the expertise required to ensure that protective relays remain the "silent sentinels" of the electrical grid throughout their operational life.

COURSE OBJECTIVES:

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

• Define the "Commissioning Sequence" for a new protection relay.
• Utilize "Secondary Injection Test Sets" (e.g., Omicron, Doble, Megger).
• Identify "Electromechanical," "Static," and "Numerical" relay types.
• Perform "Pickup" and "Dropout" tests for various protection elements.
• Execute "Time-Delay" verification against standard IDMT curves.
• Configure "Logic Functions" and "Programmable LEDs" in numerical relays.
• Troubleshoot "Communication Failures" in relay networks (IEC 61850).
• Analyze "Relay Failure Codes" and perform hardware diagnostics.
• Conduct "Scheme Tests" to verify multi-relay coordination.
• Utilize "COMTRADE" files for playback testing of fault events.
• Manage "Relay Settings" databases and version control.
• Implement "Predictive Maintenance" based on relay self-monitoring.

TARGET AUDIENCE:

This course is intended for Protection Technicians, Commissioning Engineers, Substation Maintenance Personnel, and Electrical Inspectors.

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.
