Course Description:
Electrical transformers are used to reduce voltage for various day-to-day electrical applications. More than 50 million electrical distribution transformers are located on utility poles and cement pads across the United States and Canada. Transformers serve the crucial function of transforming voltage potential to a higher or lower values to meet the appliances and machinery voltage level requirements. Improper use, maintenance and neglect can cause heavy losses to businesses as well as to the environment. This electrical transformer training course introduces basic safe operational and field diagnostics of transformers with the focus on safe operation, testing and maintenance of the distribution transformers normally installed in substations and on poles.
Students will learn safe and proper maintenance and testing procedures on power transformers. The course covers transformers used in commercial and industrial power distribution systems, including oil and dry-type units. Larger power transformers used in utility applications are also covered.
Who Should Attend:
Field and shop technicians, field engineers, supervisors and others responsible for the testing and maintenance of power transformers rated 750kVA to 500MVA and 4.16kV to 500kV.
LEARNING OUTCOMES
Upon completion of this course, the participant should be able to:
- Understand the basic theory and construction of a transformer.
- Understand turns ratios and calculate terminal voltage and current.
- Understand terminal markings and various single phase and three phase wiring schemes. (WYE vs DELTA).
- Understand transformer operation, aging and failure
- Understand transformer life cycle and maintenance planning
- Understand transformer standards
- Understand transformer factory testing and quality assurance
- Understand the electrical testing methods performed on transformers such as insulation resistance testing, excitation and power factor testing.
