Nowadays, 75% of emergencies at power supply facilities are caused by single-phase ground faults. The currently used methods of thermal imaging and ultrasonic testing do not allow accurately identify the cause of accidents in electric power distribution systems. The current search generators, due to their low power, cannot cover the entire section of the diagnosed network. The article suggests the use of digital technologies for the intelligent diagnostics of the insulation of power supply system with insulated neutral in the operating mode, allowing on-line diagnostics of the network and analyzing the data obtained for the early prevention of emergency situations. In order to avoid disconnecting sections and diagnose the system in operating mode, it is proposed to check the system using a currentlimiting capacitor, which will be connected to the live parts of each phase under voltage and accurately determine the location of a single-phase short circuit for any number of feeders. The relevance of these studies is due to the fact that, for example, during two years at one of the manufactures 19 emergencies related to single-phase ground faults were recorded. Four of these cases led to a complete stop of the production. Therefore, the development of digital technologies for the implementation of smart diagnostics of the insulation of an energized power supply system with insulated neutral will be of interest to practitioners, scientists, researchers, graduate students and other specialists seeking to study the latest achievements in smart agribusiness for their subsequent application in the real world.
The aim of our study was to develop a technology for treating animals with direct electrochemical blood oxidation. The process of direct electrochemical oxidation of blood occurs on the surface of a platinum wire electrode inserted into the blood vessel along its axis. The wire electrode is not in electrical contact with the DC power source. It is polarized by the current flowing between the additional electrodes. A solution containing a culture of staphylococci was poured into a test tube. After the passage of current through the system, staphylococci die. The cause of their death was not the electric current itself, but the products of sodium chloride electrolysis. Two chlorine atoms form a molecule that interacts with water to form an unstable hypochlorite ion, which decomposes to form atomic oxygen. Atomic oxygen is harmful to bacteria, viruses and their waste products. Positive results have also been obtained in treating dogs and calves for pneumonia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
