Overview

This interactive 3-day course combines theoretical background with practical field experience to provide engineers, managers and technicians with fundamental knowledge regarding how transformers are designed and manufactured, major transformer components, installation and commissioning, in-service and off-line electrical testing and insulating oil laboratory diagnostic testing. Doble specialists will train you to review test results so that they are clear and easy to understand. Doble encourages participants to bring their unique real-world problems for discussion.

Learn from Doble’s collective experience from working with 1000’s of transmission, distribution, generation and industrial clients globally.

Learning Outcomes

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

  • Understand transformer design and manufacturing process.
  • Learn about major transformer components such as insulating material, bushings, cooling systems, tap changers and controls.
  • Understand when to perform specific electrical off-line routine tests, off-line diagnostic tests and in-service diagnostic tests (factory acceptance, transportation, installation and over asset life-cycle).
  • Establish benchmark results to significantly increase diagnostic value of future tests.
  • Understand how to determine the condition of electrical apparatus using laboratory tests.
  • Learn how to take oil samples, avoid common pitfalls and save time and money by sampling only once.
  • Correlate electrical test result with insulating test results.
  • Interpret test results, case studies and numerous field examples.

Audience

Electrical engineers, managers and technicians working in operations, maintenance, engineering, or other service field in which knowledge of diagnostic testing methods and evaluation is required part of job responsibility.
