The study results had shown that the GPR and magnetic field of grounding system will produce detrimental effects on the breaker control system. Especially, for those poor insulation control lines, large GPR and longitudinal induction voltage during ground fault may lead to flash-over at control line terminals and thus inducing breaker mis-trip out. For the practical case in this thesis, to do well maintenance and to renew those old breakers and control lines with poor insulation situations are very important strategy for preventing breaker mis-tripping. Other protection measures from GPR and magnetic field induction interferences are important too. This study may provide useful information for planning the protection measures.

本研究结果显示变电所接地系统之GPR及其产生的磁场对断路器控制回路确有不利的影响，尤其当控制系统线路及端子若有绝缘不良，在接地故障发生的GPR及磁场纵向感应电压有可能造成闪络而引发断路器跳脱，对於本研究所探讨的案例而言，经由良好的维护或更新那些绝缘情况不良的老旧断路器及其控制线路，对於本研究所探讨的案例相当重要，而做好GPR及磁场感应干扰的防护措施亦相当重要，本研究分析结果可供规则防护措施之参考。
