Workshop on Transformer: Selection, Operation and Troubleshooting

Electrical transformers are machines that transfer electricity from one circuit to another with changing voltage levels but no frequency change. Today, they are designed to use AC supply, which means that fluctuation in supply voltage is impacted by the fluctuation in the current. So, an increase in current will bring about an increase in the voltage and vice versa.

Transformers help improve the safety and efficiency of power systems by raising and lowering voltage levels as and when needed. They are used in a wide range of residential and industrial applications, primarily and perhaps most importantly in the distribution and regulation of power across long distances. The program is designed to highlight the necessary safety procedures relating to Transformer Isolations, energizing, Testing and maintenance of transformers.

For Whom

This program is designed for skilled trades, supervisors, and Engineers involved in the maintenance of industrial power circuit breakers. Engineers and technicians from electricity supply companies, manufacturing, importing and distributing Power and Distribution Transformers, in power utilities, co-generation operators, petrochemical plants, and service managers of buildings and hospitals will also benefit from this program.

Learning Objectives

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

• Describe the basic operation of a transformer as a main component in any electrical network
• Describe the principles of construction and operation of the various types of transformers
• Explain transformer winding connections, and cooling systems for effective maintenance
• Identify the different transformer components and how they fail
• Describe turn ratios and calculate terminal voltage and current
• Describe terminal markings for various single-phase and three-phase wiring schemes
• Ensure safety practices are adhered to when carrying out electrical installation activities
• Comprehend site acceptance tests for newly installed transformers
• Carry out electrical testing performed on transformers such as insulation resistance testing, excitation, power factor testing and insulating oil tests
• Carry out safe and proper maintenance and troubleshooting procedures on power transformer
• Develop a safe maintenance procedure for transformers.
