Abstract: 본 발명은 전력 변압기의 주 보호용으로 사용되는 디지탈 비율 차동보호 계전기에 관한 것으로, 종래에는 변압기의 투입시 및 전압 회복시 그리고 변압기 병렬 투입시의 과대한 여자 돌입 전류로 인하여 계전기가 오동작 하게 되고, 또한 계전기로 부터 상당한 부분의 부하가 분리될때 변압기단자 전압 상승으로 인한 과여자에 의해서도 오동작하게 되는 문제점이 있었다. 
     이러한 점을 감안하여, 디지탈 신호 처리부를 이용하여 변류기로부터의 입력 전류를 디지탈 필터링 기법으로 고조파 분석을 한 후에 2고조파 성분을 가지고 여자돌입 상황을 조사하며, 5고조파 성분으로 과여자 상황을 조사함으로써, 변압기의 오동작을 방지하고, 내부고장시에 정확하고 신속하게 차단기로 트립신호를 보내어 회로를 보호 할 수 있게 된다. 
     따라서, 변압기 주 보호용 계전기를 다기능화 및 소형화 할 수 있고, 신뢰성 향상 및 유지보수에 편리한 효과가 있다.
