Abstract

A találmány tárgya eljárás és berendezés egypólusú földelési hibáklokalizálására csillagpontkompenzált vagy csillagpont-szigeteltvillamosenergia-ellátóhálózatnak egy leágazásában vagyvezetékszakaszában, amelynek során alkalmas módon a hálózat mindegyikmegfigyelendő leágazásának vagy vezetékszakaszának (k)csillagponteltolódási feszültségét (Une) vagy egy, acsillagponteltolódási feszültséggel (Une) arányos mérési mennyiségétés egy zérus sorrendű áramát (iok), illetve egy, a zérus sorrendűárammal (io) arányos mérési mennyiségét mérik. A találmány szerint acsillagponteltolódási feszültség (Une) és a zérus sorrendű áramok (io)mérési mennyiségeit előre meghatározott időpontokban digitalizálják,és a mérési mennyiségeket digitális alakban legalább egy elektronikustárolóban tárolják. A hibaelőfordulás előtt és után elvégzett,legalább egy-egy mérés tárolt mérési mennyiségeit egypólusú földelésihibák lokalizálására alkalmas matematikai eljárás segítségévelkiértékeik. Ó
