In the article the questions of grounding of movable электроустановок are considered and expedience of application is proved portable electrolytic grounds (PEG) for providing of the rationed resistance of grounding. In addition, description is conducted: basic directions of theoretical and experimental researches of features of work of PEG; experimental researches on a physical model and results of experimental researches on determination of form of by volume body of electrolyte in soil. The new method of determination of form of by volume body of electrolyte is offered in soil is a method of longitudinal cuts. Mathematical treatment of results of experiment by approximation of experimental curves is made by a least-squares method. The characteristic areas of by volume body of electrolyte are certain in soil. Systematization of results of experiment is made and the error of approximation is certain.
