Abstract
The utility model discloses an auxiliary ground resistance measuring apparatus comprising an iron tower wire end connecting device, a ground wire end connecting device, and a conductive connecting rod. The iron tower wire end connecting device is disposed on one end of the conductive connecting rod. The ground wire end connecting device is disposed on the other end of the conductive connecting rod. When the auxiliary ground resistance measuring apparatus is used, a grounding down lead of a measured iron tower leg is opened and then is divided into an iron tower wire end to be connected with the iron tower wire end connecting device and a grounding wire end to be connected with the ground wire end connecting device. The conductive connecting rod achieves conduction of the iron tower wire end and the grounding wire end. After the connection is carried out, a clip-on ammeter performs measurement on the conductive connecting rod rather than the grounding down lead so as to achieve lossless grounding down lead measurement.
