摘　　要：比较了间断角原理和二次谐波原理的涌流判据的性能特点，指出了间断角原理涌流判据的优良特性；This paper compares the performance of inrush current checking based on dead angle philosophy with that based on second harmonic restraint. The better performances of inrush checking based on dead angles philosophy are discussed.Emphasis is put on the key technology for realizing the microcomputer based dead angles restraint transformer differential relay. The dynamic model tests and field operations of this digital protective relay are also given.

关 键 词：变压器 差动保护 微机
