COURSE OVERVIEW:

The transition from protection design to field application requires precise setting calculations and rigorous validation. This course provides a technical deep dive into the "Applied Settings" for 32 kV and 132 kV substation relays, focusing on the practical translation of system studies into functional relay parameters. Participants will explore the mechanics of "Secondary Injection Testing," learning how to simulate fault conditions to verify the pick-up, timing, and logic of modern numerical protection devices.

The scope of this training addresses the end-to-end commissioning of protection systems, ensuring that every relay operates as intended within the wider grid. It covers the technical nuances of "Relay Setting Software," focusing on the configuration of complex logic equations and the mapping of physical inputs to virtual protection elements. The curriculum provides a detailed focus on "Scheme Verification," ensuring that participants can troubleshoot "Wiring Errors" and "Polarity Reversals" that could lead to catastrophic protection failure during a real fault.

Coverage includes the implementation of "Primary Injection" tests to verify the integrity of the entire measurement loop, including CTs and VTs. Attendees will learn to utilize "Protocol Analyzers" and "Injection Test Sets" to validate GOOSE messaging and hardwired trip paths. By combining numerical calculation with hands-on testing protocols, the course equips professionals with the expertise required to commission and maintain 32/132 kV protection systems with the highest degree of accuracy and confidence.

COURSE OBJECTIVES:

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

• Calculate "Secondary Settings" for overcurrent and distance relays.
• Configure "Numerical Relay" parameters using vendor-specific software.
• Perform "Secondary Injection" tests for 50, 51, 67, and 21 functions.
• Execute "Transformer Differential" (87T) stability and sensitivity tests.
• Verify "Restricted Earth Fault" (REF) through polarity and phase checks.
• Conduct "Distance Protection" Zone verification using R-X plots.
• Perform "Primary Injection" to verify CT ratios and circuit integrity.
• Execute "End-to-End" tele-protection testing with GPS synchronization.
• Troubleshoot "Logic Errors" in breaker failure and auto-reclose schemes.
• Analyze "Relay Event Logs" and "Disturbance Records" (COMTRADE).
• Perform "Insulation Resistance" and "Continuity" tests on control cables.
• Document "Commissioning Test Reports" for utility handover.

TARGET AUDIENCE:

This course is intended for Commissioning Engineers, Protection Technicians, Maintenance Engineers, and Field Testing Personnel.

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.
