Series reactor is installed in the 220 k V transmission line so to limit short circuit current.In this paper

the addition of current limiting reactor at the outgoing side of Yihua 220 k V power plant in Xinjiang is taken as the background.It is found by the use of electromagnetic simulation software EMTPE and through voltage analysis of the transmission line and next level line before and after the installation of the reactor that the series reactor of 220 k V transmission line has a definite influence on the power frequency voltage of the line

secondary-arc currents and recovery voltages

reclosing overvoltage in the closing operation as well as transient recovery voltage of circuit breaker of the line.
