摘　　要：为了解决1 000 kV特高压标准电压互感器的误差校准及量值传递溯源问题,笔者介绍了一种利用测量标准电压互感器的一次空载导纳及低校高的方法来确定1 000 kV电磁式标准电压互感器的误差,很好地解决了高压电磁式标准电压互感器的量值传递问题,并通过大量的试验数据论证了该方法的可行性和正确性。In order to solve the problems of error calibration, quantity transfer and traceability of 1 000 kV standard electromagnetic voltage transformers, a method for determining the error of the 1 000 kV standard electromagnetic voltage transformer is proposed by measuring the primary no-load admittance of the transformer and calibrating high-voltage device with low-voltage one. Thus the quantity transfer problem of the standard electromagnetic high-voltage transformer is solved. The feasibility and validity of this method is verified by a large number of test data.
