Condition Assessment Through Laboratory Diagnostics

Course Overview

Learn to identify and assess rapidly emerging transformer conditions with dissolved gas analysis, oil quality analysis and other diagnostic tools. This interactive, 1-day seminar combines theoretical background with practical experience to provide engineers, chemists and others who review data with the vital knowledge and hands-on examples – including case studies – needed to interpret laboratory results to detect and identify problems with oil-filled transformers, circuit breakers and power cables. Doble encourages participants to bring their unique real-world problems for discussion.

Learning Outcomes

Upon completion of this course, the participant will be able to:

  • Understand how to determine the condition of electrical apparatus using laboratory tests.
  • Discover how knowing about aging characteristics of insulating materials can help you extend asset life.
  • Learn how to take oil samples, avoid common pitfalls and save time and money by sampling only once.
  • Detect the presence of incipient-fault conditions and categorize them.
  • Find out how to assess the condition of the paper insulation.
  • Establish the correct method of analyzing moisture-in-oil results.
  • Study the significance of dissolved and particulate metals and other particle contamination.
  • Learn about the quality of new and service aged oils.
  • Learn how to identify and mitigate issues with corrosive oils.


Electrical engineers, managers and chemists working in operations, maintenance, engineering, or other service field in which knowledge of asset design, insulating liquid analysis or electrical testing methods and evaluation is required part of job responsibility.
