电子式互感器是智能电网建设的关键设备之一，其性能直接影响到数字化变电站的安全和经济效益，也是电能计量准确的必要条件。电子式互感器的输出与传统互感器不同，分为数字输出和模拟输出两种，因此传统的互感器校准方法已经不适用于校准新型的电子式互感器。文章以模拟量输出的互感器为例，创新性地提出了采用精密分流器和示波器测量比值差和相位差，并对校准数据进行了验证，测量结果满意。

Electronic instrument transformer is one of the key equipment for smart grid construction. Its performance di-rectly influences the safety and economic benefits of digital substations,and it is also the necessary condition of accurate power measurement. Different from conventional electromagnetic transformers,the output signal of the electronic instru-ment transformer can be classified into two categories,namely digital output and analogue output. Therefore,conven-tional calibration methods are not suitable for electronic instrument transformer testing. Taken the electronic instrument transformer with analogue output as an example,this paper puts forward employing precise shunt and oscilloscope to measure ratio error and phase displacement. The calibration data are verified,and the results are satisfactory.
