Abstract

This article discusses the problem of identifying the low-resistance poles without removing them from the group grounding wire, and it’s given some results of our research in this area. The main purpose of this article is to develop a more effective, less time-consuming diagnosing method. Using modern calculating techniques and comparing theoretical results with measured ones allow us to make an analysis of information take a decision. Also in this article it’s discussed the variations of the total resistanceofpoles, united with group grounding wire from the power supply frequency, depending the location of the low-resistance pole. The proposed method allows to find a low-resistance poles without disconnecting them from the grounding wire, thereby decreasing exploitation costs. The author propose the principle of total resistance variation with accordance to the different frequencies of the power source for defining a low resistance pole, situated in a group of poles with the general grounding wire. The research results can be applied by experts in the diagnosis on railway transport that involves the identification of the technical condition of catenary poles.
