Transformer Lifecycle Management
Provides advanced education to manage a maintenance program and/or lead the overall delivery and execution of that program. Build fundamental concepts to understand the transformer lifecycle from procurement through installation through end of life and assess equipment risks.
Develop expertise to create purchase and repair specifications, coordinate factory inspections, understand acceptance testing, adhere to transportation and installation requirements, create risk assessments, and make proper field or shop repair decisions. Students will be able to make informed and timely decisions regarding all aspects of a transformer and its components in order to maximize the return on investment of these assets.
You will have four days of learning consisting of multiple education formats such as classroom instruction with practical application exercises, review and understanding of a purchasing specification, review and understanding of a commissioning plan. You will be able to add an additional class (elective) of your choice that is specific to a topic, piece of equipment, or area of expertise.
You will be able to plan, develop and implement an effective transformer management plan. You will be able to participate in and direct the planning and implementation of effective system operation and maintenance programs, and become a valuable specialist in the management of equipment.
You will determine whether to purchase or repair a transformer, coordinate inspections, assess equipment risks, and determine adequate and timely repair resolutions to make appropriate capital budgeting decisions.
Participation in practical exercises, activities, and case study analysis performed in class will equip you in determining appropriate capital investments based on transformer purchase or repair options, inspections, transportation and risk analysis.

Advanced DGA Diagnostics
Advanced perspective on how dissolved gas analysis (DGA) results are interpreted – an important tool in the overall transformer maintenance program. Includes hands-on break out groups.
This class is intended to identify fault gases and what causes their formation; explain and provide examples of qualitative and quantitative interpretation of dissolved gasses. This class will also evaluate the condition of cellulose insulation and other non-routine tests, examine the role DGA plays in new oil testing and discuss procedures to obtain a representative sample from transformers, and how to mitigate risk.
Attendees are encouraged to bring their own transformer data to use as a case study for interpretation of dissolved gases or to help develop a maintenance program.
