The article provides data on the impact of high-voltage current of electric spark discharges on the culture of gummosis located on the surface of a cotton seed, special electrodes were made to determine electrical resistance, a method for conducting research experiments was developed, the liquid was from the outside of the peel, an electronic megohmmeter was used for measurement, for conducting experiments have drawn up a block diagram of the research methodology. The analysis of the works shows the absence of any data on the electrophysical parameters of the moistened pubescent seeds before sowing. Therefore, the study of the electrophysical characteristics of sown moistened pubescent cotton seeds is of scientific and practical importance for substantiating the operating parameters of electric spark treatment. Before sowing, pubescent cotton seeds are sorted (low-quality seeds are separated up to 10-15%), then moistened. The morphology and the mechanism of wetting cotton seeds are reflected in the analyzed works, and in the sectional view of the cotton seed. In the process of moistening, the main site of moisture absorption at the initial stage of moistening after backfilling is chalaza. Together with moisture, oxygen also enters the crumpled cotyledons, after which the root makes its way through the micropile. The peel protects the seed core from excessive oxygen supply. At the same time, the skin of the seed prevents the rapid flow of moisture into the seed. An electrical circuit is presented that ensures the completeness of seed treatment. And also the materials are given regarding the “electric hardening” of the water being humidified. Preconditions have been made for the automation of the seed moistening process.

The article provides data on the impact of high-voltage current of electric spark discharges on the culture of gummosis located on the surface of cotton seed, and the article presents data on the impact of high-voltage electric spark discharges on the gummose culture located on the surface of the cotton seed. In this case, cotton seeds were taken as the basis for the physical model, consisting of three component parts, respectively, having a chalazal part, a lateral part, and a micropile. In the initial period of seed treatment, moisture penetrates the inside of the seed from the outside. Studied three-dimensional volumetric figures (hemisphere, cylinder, cone, etc.), carried out a literature review and mathematical calculations determined the calculation errors. The vessels of various shapes were compared. The prerequisites for determining the calculation errors have been made.

The city of Tashkent is developing at a very fast pace, and the power supply of a new type is the subject of innovation in this direction. Commercial metering of electricity in multi-storey buildings in modern cities mainly solves the current payment problems for consumed electricity. And the main disadvantages of such networks will remain overboard. Technically competently control the common highway of a multi-storey building is necessary. Here, the commercial metering of electricity consumption does not solve the technical policy considering the development of the city. The construction of multi-storey buildings based on an individual project is growing rapidly in the city. Together with the environmental aspects of the impact of such buildings, it is necessary to address the issue of reliability in power supply. The use of power supply schemes taking into account backup power is relevant. It is proposed to take a diesel power plant as a backup source. For this, an electrical circuit of relay protection using an automatic transfer switch is proposed.

During a long shutdown of the motors, the insulation quality of the windings of asynchronous motors deteriorates due to moisture. This requires additional costs for drying the insulation of electrical machines. The signs and possible causes of malfunctions of electrical machines, as well as methods of drying insulation, are studied: Drying by external heating, Drying by heating from an external source, Convective drying, Drying by induction loss, drying using light emitters. Drying using infrared radiation is the mildest method and helps to maintain the quality of the insulation. The movement of moisture in the layers of insulating windings occurs according to the laws of heat-mass exchange, that is, heat and moisture are simultaneously transferred. In this case, heat is transferred from more heated layers to less heated layers and at the same time promotes moisture transfer. A physical and electronic model was developed to study the effect of infrared radiation on the drying process of insulation of electrical machines. The main factors influencing the process under consideration are the power of the radiation sources and the supply voltage, that is, the temperature changes in the layers of the insulated windings were studied depending on the change in the power of the emitters and the supply voltage. The created model was investigated according to the main features corresponding to the real process (even the geometrical dimensions coincide). An indispensable condition for physical modeling is the strict geometric similarity of the model and nature, as well as the equality of the corresponding similarity criteria in them.

Oiled power transformers and autotransformers 40-60 years ago are still in operation in Uzbekistan. At the same time, diagnostic methods for determining faults in transformers and autotransformers remained the same. This article partially analyzes the factors affecting the oils of power transformers and autotransformers used in the agricultural sector. It is known that transformer oil performs the functions of cooling and insulation. During use, the oil is in direct contact with air through the respiratory system. There is a process of transition of moisture and various gases in the composition of the air into the composition of the oil. By the composition of gases, it is possible to determine the reasons for the deterioration in the quality of the main and additional insulation of oil-immersed power transformers. The issues of influence on the state of insulation of marsh gases appearing inside (at the bottom) of the tank of oil transformers and partial discharges in oil-gas medium have been little studied.
