description The invention provides an experiment device and an experiment method for exploring a relation between alternating current resistance and harmonic wave frequency of a distribution transformer winding.The experiment device and the experiment method are suitable for various distribution transformers. The experiment device comprises a programmable control power supply, a to-be-measured transformer, ahigh precision electric energy quality analyzer, and an infrared thermometer. The experiment method can accurately measure three-phase voltages, currents, active power and an effective value of eachharmonic current of a high voltage side of the to-be-measured transformer as well as the temperature of a winding. In this way, alternating current resistance of the transformer winding is obtained and compared with harmonic frequency, and then a relation between the alternating current resistance and the harmonic wave frequency of the transformer winding is obtained.
