An automatic fault location method is proposed based on ftu after the circuit analysis of single line - to - ground fault in distribution networks 通过对配电网发生单相接地故障后馈线的电压、电流变化规律的分析，论文提出了基于馈线现场监控终端ftu的故障点智能定位方法。
It provides automatical management such as the backup of the system . the process of backup and recovery supports the system recover to the error point 提供自动的管理功能，如系统的备份。备份和恢复过程支持系统恢复至故障点，出现故障或灾难时，可以方便恢复至正常状态。
In the method zero sequence voltage is discussed and new principle for automatic fault location and isolation based on the zero sequence voltage is presented in this paper 该方法以馈线电压变化量为故障点定位的主要判据进行故障点自动监测与定位，并迅速隔离故障区段，恢复正常区段的供电。
Fast and accurately locating the fault point can not only restore supply quickly but also improve the reliability and safety of the overall power system and reduce economic loss 快速精确地确定故障点,不仅可以提供稳定储备,而且可以减少损失。围绕该方案所采用的技术都是经过检验的、是切实可行的。
The single - phase grounding fault frequently occurs in neutral ungrounded system , the fault line and fault location must be found to avoid a phase - to - phase short as soon as possible 单相接地故障在小电流接地系统中出现的比较频繁，此时必须尽快找到故障线路以及大致的故障点，以避免两相对地短路。
You can use the properties in this category to restart the package from a point of failure in the package control flow , instead of rerunning the package from the beginning of its control flow 检查点使用此类别中的属性可以从包控制流中的某一故障点重新启动包，而不是从包控制流的开始处重新运行包。
After the neutral point is grounded through perterson coil , it can decrease the capacitor current through fault point and the over - voltage caused by the grounding fault , which is advantage for the extinguishments of electric arc 中性点经消弧线圈接地后，有效减小了流过故障点的电容电流，减小了弧光接地过电压，有利于电弧熄灭。
Under the full recovery model , use a combination of database , differential database , and transaction log backups to minimize the number of backups that need to be applied to bring the database to the point of failure 在完整恢复模式下，组合使用数据库备份、差异数据库备份和事务日志备份可以将数据库恢复至故障点所需备份数减到最少。
After the neutral point is grounded through peterson coil , it can decrease the capacitor current through fault point and the over - voltage caused by the grounding fault , which is advantage for the extinguishments of electric arc 中性点经消弧线圈接地后，有效地减小了流过故障点的电容电流，减小了弧光接地过电压，有利于电弧熄灭。
Based on the result , the fault diagnostication according to fault record data and locating the fault position of staor wtndings are put forwar for the first time , it is innovative and practical 在此基础上，首次提出用录波数据对定子绕组匝间短路和相间短路进行故障诊断，确定故障点在定子绕组上的相别和匝数，有创新、有实用价值。
