摘要
定量分析主变空载合闸时产生的励磁涌流波形典型特征数据 ,进而检验变压器差动保护动作以及保护整定值的正确性 。
By analyzing quantitatively the typical data of the exciting inrush current waveform caused by main transformer closing without any load , the correctness of an operation of the transformer differential protection and its settings are tested to verify the identification capability of microprocessor based transformer differential protection and capability to escape away the exciting inrush current.
