1.stand for the study of the distribution of potential along the casing of wells containing u043eu0431u0441u0430u0434u043du0443u044e column, a contact probe and a reference electrode, a t eat that, with a view to enhancing the effectiveness of cathodic protection by increasing the measurement accuracy u044du043bu0435u043au0442u0440u043eu0434u043du043eu0433u043e capacity of the external surface of the column electrode u0441u0440u0430u0432 of the available column.in the interval with the inner dielectric coating and u043fu0435u0440u0444u043eu0440u0430u0446u0438u0435u0439.2. stand for 1, which was, however, that the reference electrode is placed between the two cuffs, provided with u043fu0435u0440u0435u043fu0443u0441u043au043du044bu043cu0438 valves.
