Trunova I. Receiver voltage regulation as the way of ra-tional use the electrical energy in agriculture production.

The object of research is correlation of voltage regulation index of agriculture production tech-nology processes with physical processes in electrical equipment and with economic effect index agriculture production technology proc-esses. The aim - to provide of the electrical en-ergy rational use in agriculture production tech-nology processes by means of local voltage regulation by techniques on the basis of injector transformers. Methods of researches are gener-ally accepted. The method of voltage influence definition for electrical equipment work index have been improved; economic-mathematics model of electrical equipment work in agricul-ture production technology processes, outlet voltage definition method for local voltage regulator, mathematics model of injector trans-formers work has been determined; theoretical and experimental research of it operation has been developed. Construction principles of local voltage regulators are theoretical grounded. Practical realize work results allowed to dec rease of electric energy use in agriculture production technology process by 9,42 %. The test coupon of local voltage regulator has passed trials in ag-riculture company "Snechkiv" (Kharkiv region).
