Selection, Operation & Troubleshooting of Transformers

This course aims are to provide understanding of the basic fundamentals and constructional features of Power Transformers with particular reference to the design, testing, operation and maintenance of transformers in power systems. Transformer is a very complex and valuable device with many mechanical and chemical processes taking place all the time. The course also highlights the necessary safe procedures relating to Transformer Isolations, energizing and related circuitry. Special emphasis is also placed on the Testing and maintenance of transformers.

This course is a must for utility and industrial electrical Engineers, who have the responsibility of keeping their electrical system “on-line.” This course combines theoretical and practical aspects of transformer design, operation, maintenance, testing and troubleshooting. This course gives the participant the information necessary in helping him prevent premature failure and costly unplanned outages. The participant will learn the oil and electrical test requirements and how to interpret the test data as well as setting up a proper preventative maintenance program.

The important features of the Selection, Operation & Troubleshooting of Transformers training course are:

• Developing a maintenance procedure of power transformers
• Understanding the selection criteria of transformers
• Management of all hazards associated with power transformers
• Management related issues such as risk and safety

• Explain the basic operation of a transformer as a main component in any electrical network.
• Determine different shapes and designs of transformers.
• Discuss turns ratios and calculate terminal voltage and current.
• Discuss terminal markings and various single phase and three phase wiring schemes. (WYE vs DELTA).
• Discuss the electrical testing performed on transformers such as insulation resistance testing, excitation and power factor testing.
• Discuss the various tests performed on insulating oil.
• Understand Safe and proper maintenance and troubleshooting procedures on power transformer.
• Learn practical new solutions for specifying, operating and maintaining power transformers in a utility or plant environment
• Avoid costly errors from specifying the wrong transformer for your application and from failing to recognize the importance of specifying the right core design
• Examine the possibilities of maximizing efficiency and economic performance of your transformer fleet
• Determine precise transformer specifications for every application
• Become familiar with what makes a power transformer tick
• Gain knowledge of both the underlying principles and practical applications of power transformers in today’s competitive world

This course is recommended for skilled trades, supervisors, and anyone involved in the maintenance of industrial power circuit breakers, especially: Engineers and technicians from electricity supply industry – Engineering professionals from companies manufacturing, importing and distributing Power and Distribution Transformers – Engineers and technical personnel in power utilities, co-generation operators, petrochemical plants, service managers of buildings and hospitals. Participants need no specific requirements other than the basic understanding of electricity and magnetism and circuit theory and general knowledge of nature and operation of Power Transformers.

The latest educational methods and strategies are employed. The course is designed to not only give the required fundamental knowledge but also to provide a strong background for all attendees towards practical industrial applications. The course will be highly interactive, with opportunities to advance your opinions and ideas. Participation is encouraged in a supportive environment. To ensure the concepts introduced during the course are understood, they will be reinforced through a mix of learning methods, including lecture style presentation, open discussion, case studies, simulations and group work.

Pre & Post course assessments will be used to measure the effectiveness of this training.
