abstract: introduce the phenomenon of the distribution transformer capacity tester when blind testing capacity does not consistent with the nameplate capacity,but the corrected measurement is correspond to the nameplate capacity.analyze and verify the reasons for this confusion test results.put forward the method to judge real capacity of distribution transformer with problems,which use the short circuit test with capacity tester and gb parameters required.

key words：distribution transformer; capacity; loss；
