Device for Remote and Mobile Monitoring of Electrical Grids of Agricultural Facilities

Abstract

The main methods that are used in the process of energy inspection of agricultural facilities include instrumental inspection of both the electrical grid of the enterprise as a whole and individual technological processes, electrical devices and electrical equipment. The instrumental survey allows you to get diagrams of the electrical load, record the consumption of electrical energy and investigate the main parameters of the electric grid on the enterprise at its different points. It is desirable to carry out such measurements without disconnecting the electrical devices, as this can lead to losses for the enterprise. The available instruments and complexes do not allow remote monitoring of the operating parameters of the electrical grid, are not adapted for long-term measurements in the conditions of agricultural facilities. Permanently installed metering devices, monitoring devices do not provide the necessary mobility during the energy audit. It is required to develop devices for remote and mobile measurement of operating parameters electrical grid of agricultural facilities. (Research purpose) The research purpose is in developing a device for remote and mobile measurement of operating parameters of electric grid of agricultural facilities. (Materials and methods) The article presents the analysis of literature sources, the analysis of existing means for measuring electrical energy parameters. (Results and discussion) The existing methods and technical means that allow for the study of the parameters of the operating modes of electric networks are not adapted to long-term measurements in the conditions of agricultural facilities, since they have low protection from the environment and a high cost. The article presents the developed device schematics and an experimental sample. Its tests were conducted verifying the accuracy of measurements and the correctness of the specified functions. (Conclusions) A device has been developed for remote and mobile measurement of operating parameters of electrical grid of agricultural facilities. Based on the test results, the operability of the developed device was confirmed.
