COURSE OVERVIEW:

The fundamental meaning of this course is the proactive technical management of power transformers to ensure high availability and maximize the "Asset Life" of these critical grid and plant components. Transformers are often the most expensive and long-lead assets in a facility; their failure can lead to catastrophic downtime and significant safety hazards. This course focuses on the "Physics of Degradation" in transformer insulation, cooling systems, and accessories, providing a technical framework for condition-based care.

The scope of this training involves the detailed analysis of transformer oils and solid insulation, including "Dissolved Gas Analysis" (DGA) and moisture monitoring. Participants will examine the "Thermal Modeling" of transformers and how overloading accelerates the aging of the paper insulation. The curriculum emphasizes the "Condition-Based Maintenance" (CBM) approach, utilizing advanced testing methods like "Frequency Response Analysis" (SFRA) and "Partial Discharge" (PD) detection to identify internal faults before they become failures.

Coverage includes the management of "On-Load Tap Changers" (OLTC), bushing integrity, and the implementation of "Life Extension" techniques such as oil filtration and vacuum drying. Attendees will explore the "Risk-Based" approach to transformer replacement and how to develop a "Health Index" for a fleet of transformers. By the end of this program, participants will be able to design a comprehensive maintenance strategy that ensures transformer reliability while deferring massive capital expenditures through targeted technical interventions.

COURSE OBJECTIVES:

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

• Define the core "Aging Mechanisms" in transformer oil and paper insulation.
• Interpret "Dissolved Gas Analysis" (DGA) results using Duval’s Triangle.
• Conduct "Moisture Analysis" and determine the dielectric risk levels.
• Evaluate the condition of "Transformer Bushings" and "Surge Arrestors."
• Manage the maintenance and timing of "On-Load Tap Changer" overhauls.
• Utilize "Infrared Thermography" to detect cooling and connection issues.
• Implement "Sweep Frequency Response Analysis" (SFRA) for mechanical integrity.
• Identify "Partial Discharge" (PD) activity within the transformer tank.
• Calculate the "Transformer Health Index" for fleet prioritization.
• Implement "Life Extension" techniques like oil reclamation and drying.
• Develop "Standard Operating Procedures" for transformer testing and safety.
• Design a "Contingency Plan" for transformer failure and rapid replacement.

TARGET AUDIENCE:

This course is designed for Electrical Engineers, Maintenance Supervisors, Substation Technicians, Asset Managers, and Reliability Engineers.

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.
