試驗概述編輯
繼電保護裝置是實現繼電保護功能的設備，就是指能反應電力系統中電氣元件發生故障或不正常運行狀態，并動作于斷路器跳閘或發出信號的一種自動裝置。它主要包含著下列主要的環節：①信號的采集，即測量環節；②信號的分析和處理環節；③判斷環節；④作用信號的輸出環節。
在電力系統中，如果一次系統*，而保護發生了誤動，那么將影響對用戶的可靠供電，若重負荷線路發生誤動跳閘，還有可能引起系統振蕩事故，破壞系統的安全穩定運行；如果一次系統發生了短路故障，但保護拒動，將擴大事故范圍，甚至損壞電力設備。為了使保護真正起到對電力系統的保護與控制作用，必須使保護整體處于良好的運行狀態，使得各相關元件及設備特性優良、回路接線正確、定值及動作特性正確。所以必須加強對保護的檢驗質量。
