Everything you ever wanted or needed to know about circuit breaker testing will be covered in a half-day seminar at this year’s Finepoint Test and Maintenance Training Conference, according to Jozef Levi, application engineer at Doble Engineering.

Levi will introduce circuit breaker design and function, which provides basic information for better test preparation and test results analysis. The seminar, scheduled for Wednesday, Oct. 6, will emphasize the importance of good preparation for all stages of circuit breaker testing.

Levi will encourage participants to ask questions, as he usually does when he teaches seminars. He has said that he tries to explain complicated physical processes in a simple, understandable manner.

“My most beloved professor had the ability to explain processes to attendees in such way that they ask more questions and they are intrigued to learn more,” he said. “If I succeed in forcing students to ask questions and to have a desire to learn more about the subject, I will know that I have succeeded.”

Levi earned a diploma in electrical engineering from the Electro-technical Faculty of the University of Sarajevo in 1973. Before joining Doble in 1999, he had worked with the Energoinvest Electrical Institute in Sarajevo; Energomex in Mexico City; and E Manufacturing, in Mentor, Ohio. Now, besides working as application engineer, he teaches courses in mechanical testing of circuit breakers. He is also in the process of developing new, indirect methods for detecting the condition of breaker contacts.

The Everything You Need to Know seminar will be divided in three parts: basic design characteristics of high voltage circuit breakers, testing circuit breakers, and analysis of test results.

Levi will cover different test methods and applications to detect circuit breaker characteristics, particularly breaker timing and motion. Methods include, but are not limited to:

• Timing
• Breaker Insulation
• Insulation Medium Quality
• Lubrication
• Contact Resistance

Levi will also share some case studies with different type of circuit breaker designs for real-world application of the seminar information.
