The invention relates to an intelligent distribution transformer load test method and a device using the intelligent distribution transformer load test method, and belongs to the field of distribution transformer testing. High voltage sides of two distribution transformers to be tested are connected, low voltage sides of the distribution transformers are connected through mutual inductor. The two mutual inductors are powered by a secondary side of a regulating transformer. Through adjustment of output voltage of the secondary side of the regulating transformer and the loading process of the intelligent distribution transformers, the intelligent distribution transformer load test method and the device using the intelligent distribution transformer load test method solve the problem that load testing can be achieved because short circuit operation can be conducted on the low voltage sides of the intelligent distribution transformers, and provide reference for factory test and type test of the intelligent distribution transformers.
