backup protection

基本解释

A new scheme for transformer backup protection based on longitudinal comparison principle is proposed.
提出了一種基於縱聯比較原理的變壓器後備保護新方案。
The traditional protection has some shortcomings: long operation time of backup protection, not distinguishing overload from fault of line and so on.
傳統保護存在後備保護動作時間過長和不能區分線路過載與故障等不足。
For backup protection against high resistive ground faults, there will be a dual polarized directional overcurrent relay, inverse time with instantaneous trip attachment.
對於後備保護裝置防止高阻抗接地故障，將配置一衹雙極方曏過電流繼電器，同瞬時跳牐附件的時間成反比。
