COURSE OVERVIEW:

The sudden failure of a power transformer can result in massive financial losses, environmental hazards, and grid instability. This course provides a technical forensic framework for "Post-Mortem" analysis, focusing on the identification of the root cause behind electrical, mechanical, and thermal breakdowns. Participants will explore the mechanics of "Arcing" and "Flashover," learning how to differentiate between failures initiated by external surges and those caused by internal insulation degradation.

The scope of this training addresses the full spectrum of troubleshooting techniques, from "Internal Inspections" to the analysis of "Protective Relay" event records. It covers the technical nuances of "Through-Fault" damage, focusing on the cumulative impact of mechanical stress on winding clamping and paper integrity. The curriculum provides a detailed focus on "Root Cause Analysis" (RCA) methodologies, ensuring that participants can systematically collect evidence to prevent the recurrence of similar failures.

Coverage includes the implementation of forensic tools such as "Scanning Electron Microscopy" (SEM) for particle analysis and "Dissolved Gas" history trending. Attendees will learn to interpret "Fault Pressure Relay" (Sudden Pressure) operations, analyze "Bushing" failures, and investigate "Tap Changer" malfunctions. By combining forensic engineering with practical troubleshooting workflows, the course equips professionals with the expertise required to turn asset failures into actionable intelligence for improved grid reliability.

COURSE OBJECTIVES:

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

• Define the primary "Failure Modes" for core, windings, and insulation.
• Execute a "Root Cause Analysis" (RCA) after a transformer trip.
• Identify the signatures of "Lightning" versus "Switching" surges.
• Analyze the impact of "Through-Fault" currents on the mechanical structure.
• Troubleshoot "On-Load Tap Changer" (OLTC) mechanical failures.
• Interpret "Protective Relay" data to determine fault location.
• Conduct "Internal Tank Inspections" and evidence collection.
• Identify "Corrosive Sulfur" damage on copper conductors.
• Analyze "Bushing" failures and explosive rupture mechanisms.
• Distinguish between "Static Electrification" and "Dielectric Breakdown."
• Utilize "Forensic Oil Analysis" to reconstruct failure events.
• Document "Investigation Reports" for insurance and management.

TARGET AUDIENCE:

This course is intended for Forensic Engineers, Maintenance Supervisors, Protection Engineers, and Technical Investigators.

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.
