High-voltage circuit breakers and interrupter switches are critical components in the operation, control, and protection of utility and industrial power systems from 4 kV to 765 kV. While they perform the simply stated functions of energizing and de-energizing a circuit, the technology associated with interruption of high-voltage circuits is very complex requiring sophisticated engineering to meet today's performance requirements. Mr. Tobin will review high-voltage interrupting technologies explaining the physics of different interrupting media and the associated characteristics of the switching and protective devices. You may be surprised to learn what paper, plastics, beach sand, and eyewash have in common with air, oil, sulfur hexafluoride gas, and vacuum circuit breakers.
Thomas J. Tobin received a BEEE in 1968 and a ME in Electric Power Engineering in 1969, both from Rensselaer Polytechnic Institute. He joined S&C Electric Company in 1969 and has worked on fusing, load-switching, and fault-interrupting devices with ratings from 15 kV through 500 kV, and has received numerous patents. High-voltage and high-power testing, switchgear applications, and switching transients calculations are a particular area of interest and expertise. He is currently Vice President of R&D, responsible for new product development for S&C Electric Company. Mr. Tobin is active in the IEEE Switchgear Committee and the High-Voltage Circuit Breaker Subcommittee. He is on several IEC Working Groups and is also a member of working groups of CIGRE Study Committee 13 for switching equipment. He is a Registered Professional Engineer in Illinois.
