Title:AnalysisandVerificationofKeyTechnicalIndicatorsforHigh-PrecisionTransientWaveRecordingFaultIndicators
Abstract:
Thispaperfocusesontheanalysisandverificationofkeytechnicalindicatorsforhigh-precisiontransientwaverecordingfaultindicators.Transientwaverecordingfaultindicatorsareessentialdevicesinpowersystems,usedtodetectandlocatefaultsaccurately.However,theaccuracyandreliabilityoftheseindicatorsarecrucialfortheirefficientoperation.Thus,itisimportanttoanalyzeandvalidatethekeytechnicalindicatorstoensuretheireffectiveness.Thispaperdiscussesthekeytechnicalindicators,theirsignificance,challenges,andproposesaframeworkfortheirvalidation.
