- Course 231.
- 1 Week.
- 3.6 CEU.
This course is the next step after Substation I to enhance the skills needed to perform all substation tasks including a focus on common transformer configurations.

It offers training on the components of power and distribution type transformers, including common insulating and cooling mediums and explains common transformer configurations.
Upon completion of this course, students are able to inspect, adjust and perform insulation resistance, connection resistance and over potential tests on air and disconnect switches as well as interpret results of earth resistivity tests and more.
The course will be covering:
• Identify safe work procedures
• Explain the configuration and function of common equipment found in a substation.
• Identify components of power and distribution type transformers, including common insulating and cooling mediums.
• Explain common transformer configurations.
• Perform and interpret results of winding resistance, dielectric absorption ratio, polarization index, and power/dissipation factor tests on transformers.
• Calculate temperature corrections.
• Identify ASTM requirements for testing and sampling gas and oil in transformers Inspect, adjust and perform insulation resistance, connection resistance and over-potential.
• tests on air and disconnect switches.
• Perform and interpret results of earth resistivity tests.
Who Should Attend
This hands-on course is intended for apprentices, technicians and engineers responsible for the maintenance and testing of industrial and utility substations. This course requires a working knowledge of basic electricity.
