In 2020, the cause of identification of the single-phase fault in the override line of the power distribution grid was published in IEEE TRANSACTIONS on Industry m88 sports bettingm88 live casino gamesApplication (SCI). have-to-found fault for Overhead Lines in Nonsolidly Earthed Distribution Networks。

  Single -phase ground fault(spgf)seriously affects the reliability and safety of the power distribution system。Online accurate identification of the cause of fault，Help the discovery and maintenance efficiency of weak components。This paper is analyzedspgfVarious symptom characteristics caused by typical reasons，A fuzzy reasoning system for identification of the cause of non -grounded air line failure(FIS)。On the basis of investigation of a cause of a failure m88 sports bettingm88 sports bettingof a city in China，Steady for lightning arrangers、Insbuilding Small Flash、Line horizontal discharge、Line falling mud、Line Falling Wet Sand、Line Pond, etc.6The cause of typical failure is designed with artificial grounding experiments，Collect waveform data。Multiple time frequency analysis of waveform data of various reasons，Extraction from recovery、zero current time、Transition time、Five features of distortion and randomness，Get statistical results。Based on this，establishedspgfCause recognitionFIS. m88 com live casino registerm88 com live casino registerExperimental results andbpComparison of neural network models indicates，This method has good performance and feasibility。
