The article presents a study of the effect of a resistor in a network neutral point from 6 to 35 kV on the conductive electromagnetic interference with the ground-fault current. A mathematical model is proposed.

Main problem: the organization of anti-doping education of students assumes the presence of a specialized discipline "Fundamentals of anti-doping support" and the inclusion of anti-doping topics in classical disciplines. The formation of a number of competencies in the field of anti-doping education requires new interactive forms of organization of activities that take place in the development of both disciplines of the medical and biological cycle, as well as sports, pedagogical and social disciplines. A conscious perception of the industry problems associated with the use of doping in sports and the health of the nation provides knowledge of chemistry, biochemistry, physiology, sports medicine. Purpose: study of the organization of the educational process for anti-doping support in a sports university. Methods: today, the main methodological innovations are associated with the use of interactive learning technologies. The learning process, based on the use of interactive teaching methods, is organized taking into account the inclusion of all participants in the learning process. An educational communication environment is created, which is characterized by openness, interaction of participants, equality of their arguments, accumulation of joint knowledge, and the possibility of mutual evaluation. The organization of the educational process on anti-doping support for InEU students assumes the presence in the educational program of a specialized discipline "Fundamentals of anti-doping Support" and the introduction of components of anti-doping education in already established disciplines. Results and their significance: the organization of the educational process on anti-doping support for InEU students assumes the presence of a specialized discipline "Fundamentals of anti-doping Support" in Educaional Program and the inclusion of components of anti-doping education in the formed disciplines.

In this regard, there is a need to search for new ways and scientific and methodological developments to rationalize methods of teaching game techniques and the development of physical qualities, such as coordination abilities, which are well developed at the initial stage of training in rhythmic gymnastics. The aim of the study was to determine the influence of rhythmic gymnastics on the development of coordination abilities in young football players aged 7-10. The main method of obtaining results in the study of motor qualities was testing. It allowed us to determine the level of functional state of the cardiovascular system, as well as the level of development of coordination abilities, namely, rhythm, plasticity, accuracy, balance and orientation in space. As a result of the experiment, the effectiveness of the developed program was revealed. The results of the study showed that the use of elements of rhythmic gymnastics bring a variety of tools to the lesson and allow the coach to fully meet the physiological requirements of this age. The rhythmic gymnastics program can be widely used in children's football institutions, as the level of coordination abilities of athletes increases in the course of training, and better conditions are provided for the formation of skills to manage their movements, that is, to act purposefully, productively, and economically.

In the implementation of social policy, the most common practice in foreign countries is the payment of a part of the cost of the service by the recipients of social services. However, this decision raises some doubts. After all, these services are for members of the public who are unable to take care of themselves and generally cannot earn a living. On the other hand, when the state bears the costs, there is a risk of overconsumption. The decision on the extent to which a beneficiary of a social care service should share in the costs of social services depends on a variety of factors: criteria for social justice in the country and perceptions of social justice (for example, public opinion about whether unpaid social care services should be provided to all or only the poor), from a group of people in need of social care (social care services for children from social risk groups, especially for people with severe disabilities, are usually free of charge), from the economic ability of the state to provide free social services, etc. The purpose is to study the positive foreign experience in the provision of social services in modern conditions. Determine the role of the state as the dominant body in the implementation of social policy. The study is based on the principles of a systematic approach. Also, when writing the article, the dialectical method of cognition, the methods of scientific generalization and classification, the method of comparative analysis were used. Systematization and generalization of foreign experience in the provision of social services, taking into account the definition of its main goals and objectives, show that the changes taking place in the field of social protection in developed countries over the past two decades already indicate that the model of organizing social assistance, based on the dominance of market relations, operates in many countries. Under the hierarchical model, the organization of social services is based on a vertical division of responsibility and state functions, and the state has a monopoly on providing social care services and funding state or non-state care institutions. However, in recent decades, social assistance services have already been purchased from market participants and funded not by the state, but by the person in need of social assistance. However, such a market is not pure, since the state is involved in both the purchase and pricing of the service.
