提出了一种利用相互负载法对两台智能化配电变压器进行负载试验的方法，该方法使两台智能化配电变压器互为负载，外接电源不断改变负载工况，解决了配电变压器与智能电子设备(IED)无法在同时工作的情况下进行负载试验的问题，通过智能配电变压器本身的IED采集负载试验下的数据进行参数计算，计算结果表明，其与传统的负载试验结果相比误差在1%以内。

This paper proposed a kind of method which utilized the mutual load method to carry out the load test for two sets of intelligen-tized distribution transformers. This method enabled two sets of intelligentized distribution transformers to be the load for each other. The external power supply was connected to change the load conditions, to solve the problem that the distribution transformer and intelligent IED couldn’t work together at the same time of load test. This paper calculated the parameters with the IED acquisition load test data in intelligen-tized distribution transformers. The calculation results show that compared with the traditional load test results, the error of this test results is less than one percent.
