Improving the reliability of electric power supply has always been one of the main tasks. The relevance of the task of ensuring of reliable electric power supply is particularly high for the agricultural enterprises with industrial type, especially for the livestock farms. High technical and economic requirements to the quality and efficiency of agricultural technological processes determine the necessity of solving the problem of ensuring reliability of the electric power supply systems of the enterprises involved in agricultural production. In such systems there is a great number of switches, devices of protection and control. These devices operate in heavy-duty with a large number of various perturbations, leading to a substantial reduction of the standard life and the occurrence of switching malfunctions, causing to a decrease in ex-operational reliability. The known methods and technical means of control and registration of emergency situations are not effective enough, narrowly specialized, complex, expensive. Consequently, the development on the basis of new methods of control effective technical means to remotely control the state of electrical equipment in operation, operated in terms of agriculture is a relevant and practically important task nowadays. In this article, the authors propose a new method of remote control of switch's state in the partitioned lines. This method allows to control the state of the switch upon the occurrence the short circuit, happened after the installation of the switch. The proposed method of control is implemented in the remote control of switches of the power lines on the basis of the analog-to-digital converters with following processing of the receiving data with special computer program. The implementation of this method remote control switch enables to increase the reliability of power supply of agricultural consumers.
