摘　　要：参照电力变压器经济运行国家标准GB/T 13462-2008,建立了变压器经济运行判别模型及对经济运行区进行了划分。利用单片机技术完成了对电压、电流及功率因数等参数的测量和经济运行状态的判别。对变压器经济运行测试仪的硬件电路和软件结构进行了分析。实际测量表明,该测试仪操作方便,测量结果正确,具有较好的实用性。Refer to the national standard of the power transformer economic operation GB/T 13462 -2008, the diseriminant model of economic operation of transformer is established and the economic operation zone is divided. Using the microcontroller technology to complete the measurement of voltage, current and power factor and the judgment of economic operation state. The hardware circuit and software architecture of the transformer economic operation tester are analyzed. The actual measurement shows that the measuring instrument is easy to operate, the measurement results are correct, and has better practicability.
