System and method for simultaneously testing plurality of reactors

The invention relates to a system for simultaneously testing a plurality of reactors. The system comprises a synchronous generator set, and is characterized in that the output end of the synchronous generator set is connected with the low voltage a-x of an intermediate test transformer; the high voltage A of the intermediate test transformer is connected with the head end of the compensation capacitor bank C; the high voltage X of the intermediate test transformer is connected with the tail end of the compensation capacitor bank C; and a first test branch, a second test branch,..., and an nthtest branch of each reactor are sequentially arranged in parallel between circuits behind the head end and the tail end of the compensation capacitor bank C. The invention also relates to a method forsimultaneously testing a plurality of reactors, which comprises the following steps of: calculating the reactance value of each shunt reactor according to an impedance calculation formula Z = U/I; and calculating the loss val
