Hands-On Competency Based Training In Insulation Power Factor For Powertransformer

This 24-hour practical course provides you with methods and procedures used internationally. Predictive, periodic or condition based (on line diagnostics and monitoring) maintenance are basic methodologies in substation maintenance. The course is for a beginner, or an experienced maintenance technical staff who wants to be effective as a test engineer, and for an advanced test engineer to learn new concepts in power transformer testing, oil recycling or oil filtering concept, and basic results interpretation. The course will also focus on issues related to causes of bushing breakdown, arresters, oil, impedance, leakage reactance and most of all short circuits rating a transformer can withstand.


At the end of the program, the participants will be able to:
• Discuss basic transformer fundamentals.
• Understand the latest transformer technology.
• Discuss making of a transformer.
• Enumerate basic oil and transformer testing methodology protocol.
• Identify and solve concerns of on the job practices.
• Discuss equipment application.
• Demonstrate actual IPF methodology and testing procedures
