Transformer is a kind of special equipment that realizes the transformation, distribution, transmission, measurement and compensation of electric energy based on electromagnetic induction principle. It has the advantages of high mechanical strength, strong load capacity and low power loss, and is widely used in electric power industry, industrial production, transportation industry and other fields. In this paper, the structure, working principle and output characteristics of transformer are analyzed, the relationship between the secondary voltage and the primary voltage, the number of turns of the primary coil under the open circuit; secondary current and primary current, the number of turns of secondary coil in short circuit; primary current and secondary current under load were studied experimentally, the output power of transformer is measured. Combined with trans-former theory, the experimental results are analyzed in detail.
