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.
