摘　　要：传统上电压互感器和电流互感器进行检定时为单个逐台检定,其检定接线较为复杂,而且必须按检定规程进行试验电压或试验电流的逐点升降和测试数据,单台校验占用的时间较长,检定效率低。为了提高检定效率,研究和设计了一种多台电压互感器和电流互感器检定系统,可以对多台电压互感器和电流互感器同步进行检定。介绍了该检定装置的误差接线图,达到了通过一次性接线,实现互感器的同时测量的目的,通过对多台电压互感器和电流互感器的检定数据和原有检定数据进行比对分析,检验结果完全满足检定规程要求。Verify the traditional voltage transformer and current transformer device for single layers and verification, the verification wiring is complex, and must according to the verification regulation of test voltage or current test by lifting and data, occupy a single check for a long time, the testing efficiency is low. In order to improve the verification efficiency, we study and design a multi - stage voltage transformer and current transformer calibration system,which can be used to test the synchronization of multi - voltage transformer and current transformer. Introduces the calibrating device error wiring diagram, reached connection to achieve simultaneous measurement of transformer, through comparison and analysis the test data of a voltage transformer and the current transformer and the original test data. The test results completely meet the regulation requirements by a single plurality of verification
