10. Q&A and Discussion

• Interactive session for participant queries and discussions
• Sharing experiences and lessons learned

At the end of this course, participants can:

• Work with KAVOSH T22
• test a power transformer based on standards
• evaluate the condition of a power transformer based on test results
• distinguish between different errors in the power transformer

Before starting this class, we recommend that you:

• basic knowledge about IEC60076 and IEEE C57.152 standards
• have the basic knowledge of transformer operation

• We provide you with writing supplies.
• All necessary testing equipment and devices will be provided during the course, and participants will have the opportunity to gain practical experience through hands-on demonstrations and troubleshooting exercises.

*Note: The course outline and schedule may be subject to adjustments based on the specific needs and requirements of the participants.
