Available in PDF, EPUB and Kindle. Book excerpt: This paper reviews the history of high voltage circuit breaker technology, from bulk oil circuit breakers of the early 1900s to sulfur hexafluoride (SF6) breakers of the modern era. It focuses on the evolution of SF6 technology and its application to the low temperature conditions found in Canada, and includes information on SF6 properties, arc quenching techniques, types of operating mechanisms, behavior of SF6 at low temperatures, and the use of gas mixtures such as SF6 and nitrogen in circuit breakers. The paper then outlines special switching applications for SF6 breakers, the factors to consider in selecting high-voltage and extra-high-voltage SF6 breakers, standards and tests used in evaluating circuit breakers, and future possibilities for circuit breaker technology such as wider application of electronic components and synchronous closing.
