Abstract：This paper analysis of two transformer wiring group, the ratio is not the parallel operation of circulating current, impedance voltage and load distribution of parallel operation. According to the parameters of the 35kV transformer of 20MVA and 6.3MVA in two substations, the impedance voltage deviation and the load distribution in parallel operation are calculated. Through field test verified the transformer capacity of more than 3 times, in the same ratio, meet the wiring group and impedance voltage deviation under the condition of parallel operation.
