Обосновать целесообразность совершенствования методологии выполнения заземляющих устройств. Исследовать влияние минеральной проводящей смеси на коэффициент сезонности. Проанализировать результаты экспериментальных исследований. Оценить снижение сопротивления тестового заземляющего устройства по отношению к контрольному. Предложить эффективные технические решения для снижения значения сопротивления заземляющих устройств. МЕТОДЫ. При решении поставленной задачи проведен ряд натурных экспериментов по измерению значений сопротивлений заземляющих устройств экспериментальных заземлителей, после обработки смесью околоэлектродного объема грунта для оптимизации сопротивления заземлителя. РЕЗУЛЬТАТЫ. Разработан состав смеси для нормализации (уменьшения) удельного электрического сопротивления грунта, содержащей гидростабилизирующие добавки и низкодиспергированные проводящие вещества. Предложены аналитические выражения для оценки эквивалентного удельного электрического сопротивление грунта с учетом замещения части грунта минеральной проводящей смесью. ЗАКЛЮЧЕНИЕ. Применение смесей на основе гидролизованного полиакрилонитрила наиболее эффективно при использовании совместно с заземлителями, глубина заложения которых меньше глубины промерзания грунта, то есть находящимися в слоях грунта с наибольшими сезонными колебаниями, и будет расти при увеличении площади контакта таких заземлителей с грунтом, обработанным гидролизованным полиакрилонитрилом. Дополнительное уменьшения коэффициента сезонности для вертикальных составных заземлителей, по-видимому, обусловлено влиянием смеси на их части, смонтированные вблизи поверхности грунта. Применение комплексных смесей, содержащих, помимо гидростабилизирующих добавок, также и низко диспергированнные проводящие вещества, позволяет до трех раз уменьшить сопротивление заземляющих устройств в сравнении с контрольными, сгладить сезонные колебания сопротивления ЗУ и капитальные затраты на монтаж заземляющих устройств путем уменьшения количества электродов и размеров территории, на которой они располагаются.</p></abstract><trans-abstract xml:lang="en"><p>THE PURPOSE. The purpose of the article is to define the reasons to improve the system of grounding devices design. Author studies technical decisions that reduce grounding resistance values. Results are given researches how a mineral conductive mixture, that normalizes grounding, influences a seasonal coefficient. Analysed the results of the experimental surveys. Аlso evaluates a test grounding devise’s resistance decrease compared to the resistance decrease of a control grounding device. METHODS. While solving the above problem, a number of field experiments were carried out to measure the resistance values of experimental circuit grounding devices after their near-electrode soil space had been treated with the mixture that improves the resistance of a grounding wire. RESULTS. The composition of the mixture that normalizes (reduces) soil electrical resistivity has been developed, it has contained hydro-stabilizing and lowdispersed conducting additives. There has been proposed the analytical expressions to evaluate equivalent soil electrical resistivity values after aporton of soil had been submitted by the mineral conducting mixture. CONCLUSION. The use of the mixtures based on hydrolyzed polyacrylonitrile is most effective together with the grounding wires buried in soil no deeper than the soil freezing depth that is located in the soil layers with maximum seasonal fluctuations, and will increase with the increase of the contact area of such grounding wires with the soil treated with hydrolyzed polyacrylonitrile. Additional decrease of a seasonal coefficient for the vertical compound grounding wires apparently is due to the mixture influencing their parts mounded near the ground surface. The use of complex mixtures containing both hydro-stabilizing additives and low-dispersed conducting substances allows up to three times decrease of the resistance values of a grounding device compared to a control grounding device, it allows to even seasonal fluctuation of resistance of a grounding device, and to decrease mounting capital investment for a grounding device by means of the decrease of the number of the electrodes and the territory on which they are located.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электрические станции и электроэнергетические системы</kwd><kwd>заземляющее устройство</kwd><kwd>удельное электрическое сопротивление грунта</kwd><kwd>заземлитель</kwd><kwd>околоэлектродное пространство</kwd><kwd>гидростабилизирующие вещества</kwd><kwd>коэффициент сезонности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electrical stations</kwd><kwd>electrical energy systems</kwd><kwd>grounding device</kwd><kwd>soil electrical resistivity</kwd><kwd>grounding wire</kwd><kwd>near-electrode soil space</kwd><kwd>hydro-stabilizing substances</kwd><kwd>seasonal coefficient</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Найденов А.И., Дмитриев Е.А.
