Oil – Immersed Power Transformer Maintenance: Analysis of Insulating Oils

Click here to REGISTER

Course Duration: 1 day (8 hours)

Test-transformer-oils

This 8-hour practical course provides you with methods and procedures used internationally in evaluating data obtained on power transformer insulating oils. This course will equip attendees with the knowledge of what is happening inside the transformer up to mitigating possible severe problems that may occur in the transformer; without opening it by just utilizing test data obtained in oil laboratories. Basic information on previous technology and the current technology in insulating oils will also be discussed as to help engineers be safe at site and continue safe operation of the substation.

This will also be discussing condition-based maintenance done on oil-filled power transformer and the insulating oil itself. Moreover, analyzation of the data on lab tests done in insulating oils is the focus of the course. Using correct guidelines, analysis and recommendation is very essential to predict failure modes of the transformer.

 

Who should attend?

This course will enhance the understanding and increase competencies for:

  • Electrical consultants that gives technical advice on maintaining substation apparatus to clients.
  • Engineers & technicians in the utility, transmission and generation sectors, that operate and maintain oil filled power transformer in substations.
  • Engineers and electricians in commercial and industrial field that maintains oil filled power transformers.
  • Electrical engineering graduates who would like to be test and applications engineers and Technicians for substation.

Course Objectives:

At the end of the program, the participants will be able to:

  • Have basic knowledge about transformer insulating oils.
  • Know different characteristics of transformer insulating oils.
  • Have knowledge on what tests to conduct in insulating oils.
  • Know proper sampling techniques in transformer tanks.
  • Interpret laboratory data and correct present abnormalities in the system.
  • Knowledge in present technologies in transformer and transformer oil maintenance.
  • Safely maintain and continue good operation of oil immersed power transformer in their facilities.
