Power Transformer Testing, Diagnostics and Maintenance

Power Transformer Testing, Diagnostics and Maintenance

This One-day course is designed to help engineers understand the construction and maintenance (planning, testing and diagnostics) requirements for power transformers. Anyone directly involved in maintaining transformers or those requiring an understanding of the various tests and or analyzing test results will gain a better understanding of best maintenance practices as required by industry accepted standards.

Training program is based on: (1) Canadian Standards Association: CSA Z463- Standard for Maintenance of Electrical Systems; (2) Canadian Standards Association: CSA Z462- Standard for Electrical Safety; (3) National Electrical Testing Association (NETA): ANSI/NETA 2019 Standard for Maintenance Testing Specifications and (4) Professional Electrical Apparatus Recyclers League: Reconditioning Standards for Electrical Equipment.

Each student receives three comprehensive binders of reference material including maintenance frequencies, PEARL test standards and test forms.


Objectives

After the training, the successful candidate will be able to:

  1. Understand the difference between Run to Failure, Predictive and Preventive maintenance programs
  2. Perform multiple tests as per industry standards
  3. Be able to recognize deficiencies and take/recommend corrective action
  4. Work safely

Who should attend:

This training is recommended for: Testing and commissioning engineers, industrial electricians, electrical engineers, substation technicians, substation engineers, field engineers, managers and substation supervisors.

Please note that his training can be modified to suit your specific needs. We will be happy to conduct a needs analysis with you to determine your specific requirements. It can be conducted either on-site or off-site.
