摘要
提出一种电力变压器保护新方法，系通过一个专门设计的继电保护单元来辨识故障所产生的高频暂态电流，进而对变压器进行故障辨识和保护。基于ＥＭＴＰ的数字仿真验证了其有效性。
This paper presents a new technique for transformer protection based on the detection tuned to a band of high frequencies, is connected to the transformer through Cts on both high voltage and low voltage sides of the transformer utilised to capture fault generated high frequency current transient signals, the differential and average currents between the two sides are then calculated to distinguish internal or external fault to the protected transformer.
