Summary:The present invention relates to a method of an apparatus for measuring the composite ground resistance of a neutral wire of a distribution line in operation, the apparatus comprising: an alternating current power source which can vary the magnitude of current in order to input a current into a measurement point; a measuring instrument for measuring the inputted current and voltage; and an insulated operating rod for contacting lead wires for a current supply and voltage measurement with a neutral wire. L'invention concerne un procédé pour un dispositif de mesure de la résistance de terre composite d'un conducteur neutre d'une ligne de distribution active, le dispositif comprenant: une source d'alimentation en courant alternatif, qui peut faire varier l'amplitude du courant afin d'appliquer un courant à un point de mesure; un instrument de mesure pour mesurer le courant appliqué et la tension, et une tige de commande isolée servant à mettre en contact des conducteurs avec un conducteur neutre pour mesurer le courant appliqué et la tension.
