At the end of this course, participants will be able to:

• Understand typical failure modes associated with Cables, Switchgears and Transformers.
• Understand typically used on- and off- line diagnostic tests for condition monitoring of Cables, Switchgears and Transformers.
• Understand the interrelationships of various on- and off- line diagnostic tests.
• Understand the interpretation of test results.

This course is specially designed for Engineers and Technologists dealing with Operation, Maintenance & Testing of Switchgears, Cables and Power Transformers.
