This comprehensive 2-day course focuses on current transformers (CTs) used in high-voltage equipment. Participants will gain a deep understanding of the structure and operation of CTs, common failures that can occur, advanced diagnostic tests for assessing CT performance, and the calibration methodology for ensuring accurate measurements. The course combines theoretical knowledge with practical on-site training to enhance participants’ skills in CT diagnostics and calibration.
This course is designed for electrical engineers involved in commissioning tests, consultation, and design of high voltage substations, and general managers of power grid companies. In addition, it is recommended for young engineers who want to work with current transformers.
1st Day:
Morning Session:
- Introduction to Current Transformers (CTs)
- CT Structure and Operating Principles
- Types of CTs and their Applications
- CT Failures: Causes and Effects
Afternoon Session:
- Diagnostic Testing of CTs: Overview and Importance
- Primary Injection Test

- Excitation Test
- Ratio and Polarity Test
2nd Day:
Morning Session:
- Advanced Diagnostic Tests for CTs
- Saturation Test
- Burden Test
- Remanence Test
- Frequency Response Analysis (FRA) Test
Afternoon Session:
- CT Calibration Methodology
- Calibration Standards and Procedures
- On-Site CT Calibration Techniques
- Practical Exercises and Case Studies
- Q&A Session and Course Review
Note: The course includes hands-on exercises and practical demonstrations to reinforce the concepts covered. Participants are not required to bring their own test devices, as our all-in-one testing solution will be provided for the hands-on exercises and practical training.
By attending this course, participants will enhance their understanding of current transformers, gain proficiency in conducting diagnostic tests, and develop the skills needed for accurate CT calibration.
At the end of this course, participants can:
- Work with KAVOSH T22
- test a current transformer based on standards
- evaluate the condition of a current transformer based on test results
Before starting this class, we recommend that you:
- basic knowledge about IEC61869
- have the basic knowledge of current 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.
