Seminar: Electrical Field Tests for Transformers
|
Hosted by Southern California Edison (SCE)
 This one day seminar at Southern California Edison (SCE) will offer a comprehensive review of traditional electrical field tests for transformers. For learning purposes we focus on both apparatus and diagnostic principles.
Participants will be introduced to the most modern and effective test techniques and practices that can be applied to power transformers today. Participants will learn transformer theory, diagnostic test methods, and data analysis strategies. All subjects presented are adequate for all levels of expertise, and all examples are derived directly from field experiences.
This course is appropriate anyone involved with power transformers. Anyone who is involved with electrical diagnostic testing of transformers is welcome to attend.
