Abstract
Non-traction consumers include signaling, centralization and blocking devices, power and lighting loads of intermediate stations, office and household buildings, locomotive and wagon depots. The obtained values of the parameters are planned to be used later in the development and theoretical justification of the method for searching for cable damage points under the conditions of galvanic and inductive influence of electrified railway transport. To achieve this goal, experimental studies were carried out in laboratory conditions using the twoelectrode method, when using which there is no need to take into account the parameters of an additional electrode. Formulas are derived to determine the resistance and capacitance of the metal-electrolyte interface. As a result of the experiment, the dependences of the transient parameters at the point of damage to the copper core of the VVG cable were obtained. The obtained values of transient parameters at the point of damage to underground cables of power supply of railway transport will be used in the development and scientific substantiation of a method for finding cable damage points under the conditions of galvanic and inductive influence of the electrified railway transport.
