Objectives The relevant behaviour of a high-power circuit-breaker with respect to its ability to interrupt short-circuit current is mainly restricted to a short time window of a few tens of microsecond. The breakers were subjected to standard IEC short-line fault tests in a high power laboratory. From the database of test results, new empirical arc models are derived, eg based on the series connection of classical modified Mayr models.
Show all documents This electric arc is a complex phenomenon where lots of physic interactions take place in a very short time. Over the years, as our knowledge of the interrupting process progressed, many techniques have been developed to test the circuit breakers and simulated arc model. In this paper, modeling of the electric arc and models of high voltage circuit breakers Kema, Schwarz, Schavemaker has been studied. Using the concept of negative feedback, and use a new method to improve the break situation of the breaker on Schavemaker model is presented and results have been extracted.

The need for a second edition arises from the fact that, although it is generally recognized that circuit breakers represent a relatively mature technology there are some areas of thls technology where changes are inevitable and where some of these changes take place continuously.

Eaton has dedicated years of research, design, enhancement and testing to create a family of VCP-WG circuit breakers that meet and exceed the service duty requirements of generator circuit application defined by IEEE. Breakers are designed to meet the strict service duty requirements set forth by IEEE for generator circuit applications, including: generator circuit configuration, high continuous current levels, unique fault current, and voltage conditions.
