Experiment device and experiment method for exploring relation between alternating current resistance and harmonic wave frequency of distribution transformer winding

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.
