COURSE DESCRIPTION: This 16-hour practical course provides you with methods and procedures used internationally in maintaining and testing power transformers in substations.This course will be discussing the difference and importance of Predictive, Periodic and Condition based maintenance in transformer; that may help maintenance personnel in planning and executing maintenance programs in power transformers. The course will also be focusing on the basic theoretical concept of transformers, how they are manufactured and know different part to maintain. The course will teach attendees to conduct correct testing procedures, what test to perform, evaluation of test data versus international guidelines and mitigation of findings. The course content does not include intensive DGA (dissolved gas analysis) and oil tests evaluation.

In this technical training, participants will be guided on how to become a knowledgeable maintenance engineer and improve his knowledge based on international standards to safely maintain and prolong power transformers in their respective fields.

This course will enhance the understanding and increase competencies for:
     A. Engineers & technicians in the utilities handling substation maintenance
     B. Engineers and electricians in commercial and industrial maintenance
     C. Electrical consultants and designers and electrical project managers
     D. Electrical engineering graduates who would like to be test engineers and Technicians for substation

At the end of the program, the participants will be able to:
     A. Discuss basic transformer theoretical fundamentals.
     B. Know different parts of the transformer, what to look and what to maintain
     C. Know different international standards used for evaluating transformer test results.
     D. When to execute transformer maintenance and diagnostic testing-in timely manner.
     E. Enumerate basic oil and transformer testing methodology protocol.
     F. Know different testing methodologies and correct testing procedures.
     G. Identify and evaluate obtained results
     I. Discuss test results and know basic corrections in findings
