COURSE OVERVIEW:

The strategic management of power transformers requires a transition from reactive repairs to advanced prognostic health monitoring. This course provides a technical framework for "Condition-Based Maintenance" (CBM), focusing on the interpretation of chemical and electrical signatures that indicate internal degradation. Participants will explore the mechanics of "Cellulose Aging," learning how to utilize furanic analysis and degree of polymerization (DP) estimates to determine the remaining technical life of the winding insulation.

The scope of this training addresses the full spectrum of diagnostic tools, including "Dissolved Gas Analysis" (DGA) and "Frequency Response Analysis" (FRA). It covers the technical nuances of "Dielectric Frequency Response" (DFR), focusing on the quantification of moisture in the solid insulation and the impact of oil acidity on the rate of aging. The curriculum provides a detailed focus on "Lifetime Extension" strategies, ensuring that participants can evaluate the cost-benefit of refurbishment, oil reclamation, and online monitoring systems.

Coverage includes the implementation of international standards (IEC and IEEE) for the classification of transformer health indices. Attendees will learn to utilize "Partial Discharge" (PD) measurement to locate incipient faults, manage "Corrosive Sulfur" risks, and perform "Recovery Voltage Measurements" (RVM). By combining chemical science with high-voltage engineering, the course equips professionals with the expertise required to maximize the return on investment for the grid's most expensive assets.

COURSE OBJECTIVES:

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

• Define the primary "Aging Factors" for transformer oil and paper.
• Interpret "Dissolved Gas Analysis" (DGA) using Duval’s Triangle.
• Execute "Frequency Response Analysis" (FRA) to detect core movement.
• Utilize "Tan-Delta" testing to assess global insulation health.
• Calculate the "Degree of Polymerization" (DP) from furan concentrations.
• Perform "Moisture Analysis" in oil using Karl Fischer Titration.
• Utilize "Dielectric Frequency Response" (DFR) for moisture in paper.
• Identify the risks of "Corrosive Sulfur" and copper sulfide formation.
• Execute "Partial Discharge" (PD) acoustic and electrical mapping.
• Implement "Oil Reclamation" and "Passivation" strategies.
• Calculate the "Health Index" for a fleet of power transformers.
• Develop a "Life Extension" roadmap based on diagnostic data.

TARGET AUDIENCE:

This course is intended for Asset Managers, Transformer Specialists, Substation Engineers, and Maintenance Planning Managers.

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.
