Résumé

Learn how to use the CT Analyzer effectively to test and analyze current transformers.  This course will also provide you with an understanding of the standards that apply to CT and see how the test results relates to the CT class and ratings.

Objectifs

  • Performing testing of current transformers using the CT Analyzer 
  • Evaluating test results
  • Creating customized reports using the CT Analyzer PC software

Information

You will receive a personal email with all course information such as agenda and route directions shortly before the training course.

OMICRON’s CTA training course is designed to provide the essential information needed to “assess” the condition of your current transformer assets. Participants will be introduced to the function and operation of the OMICRON CTA. Participants will learn current transformer theory, test methods, and data analysis strategies, which includes the most up to date techniques and practices that can be applied to current transformers. All subjects presented are adequate for all levels of expertise, and all examples are derived directly from field experiences. This is a comprehensive one-day training course, and will include both classroom and hands on testing components.

 The training will consist of 5 components.

  • Introduction to Current Transformers
  • Performing CTA Measurements
  • Analysis and Interpretation of CTA Results
  • Operation of CTA Instrument
  • Hands on Current Transformer Testing
