“…While further elaborately studying trends with ABB and GCB, A. Kobayashi et al [3] suggested a method for obtaining surge voltages from chopped currents. Studying the mechanism of multireignition by using VCB, M. Murano et al [4] explained that the high-frequency chopping properties of circuit breakers are closely related with surges.…”

Using a 300kV puffer-type gas circuit breaker (GCB) combined with a 275kV-1 5OMVA shunt reactor or a test air core reactor at a laboratory, the authors measured surges during reactor current interruption. Such surges as chopping current, single reignition, and multireignition surges were observed. To explain the mechanisms of these surges, the authors measured precisely highfrequency reignition currents with the help of an optical device. Multireignition surges seem unlikely to occur in actual fields.

The paper reviews some of the theory l e a d i m f i n i t i o n of a ChUppkng " b e t i related to the chopping behaviour of circuit breakers interrupting small inductive currents. The possibility of using this number to model circuit breakers in digital calcu lations is discussed, a comparison being made with the alternative of simulating the dynamic behaviour of cifl cuit-breaker arcs by means of differential equations. The importance of a correct appraisal of the frequency dependence of circuit parameters, specially capacitances, in both methods, is demonstrated with the aid of an example.
