Advanced Transformer Maintenance and Planning
This course will get the student familiar with the substation and system equipment, as well as additional understanding of transformer design and construction. This course provides the advanced knowledge and develops the skills to identify and analyze / interpret chemical test results, identify maintenance recommendations based on chemical and electrical tests, manage service specifications, and make critical maintenance / planning decisions.
This course provides the knowledge and develops the skills necessary to identify and interpret test results, manage service specifications, and make critical maintenance decisions. It takes you beyond the foundational concepts taught in the Half Century Transformer Applied Maintenance, preparing you for administrative roles as well as direct maintenance. Go beyond reactive transformer maintenance to proactive management of your critical power assets.
You will be able to make recommendations based on analysis of chemical and electrical test results, learn the reactive, predictive, and preventive maintenance of transformers, and develop a cost-effective maintenance plan to prolong the reliable life of the transformer.
You will have four days of required learning consisting of multiple education formats such as classroom instruction with advanced case study analysis, practical application exercises, group discussions, break-out activities, interactive electrical test demonstration and learning, as well as a tour of a Vacuum Oil Purifier (Rig) with Vacuum Fill Demo. 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 maintenance program. You will review electrical test reports and understand the significance and applicability of those reports to the maintenance program. You will also learn to interpret oil analysis test reports, including DGA reports, and formulate an appropriate diagnosis and response concerning the next steps in the maintenance program.
Participation in practical exercises, activities, and case study analysis performed in class will equip you in planning and implementing a maintenance program based on oil and electrical test results.
