Abstract Shunt reactor interruption by circuit breakers may produce current chopping and cause severe overvoltages. The four-legged reactor interrupting transients were elucidated with equivalent circuit analysis, and the mechanism of beat frequency oscillation was also characterized, further, a 3-D portfolio of the beat frequency, specifically regarding shunt reactor interrupting with either a short line distance or a long transmission line, was given to describe the variation trend versus the shunt reactor's parameters. Based on the available parameters from an installed 750kV transmission line in China, simulations of the four-legged reactor interruption process were carried out with adoption of an appropriate arc model for SF₆ circuit breakers, and the scenario of the switching overvoltages was presented for two different kinds shunt reactor interrupting. The research results present useful reference for future construction and operation of the extra high voltage(EHV) and ultra high voltage(UHV) transmission lines.

Key words： Shunt reactor interrupting neutral reactor arc model beat frequency oscillation
