Guseva H. An improvement of methods of measuring of electric sizes is in the system of power supply

Dissertation is sanctified to the improvement of methods of measuring of rejection of tension, power-factor and transient, with the purpose of increase of authenticity of results of measuring, observance of the requirements produced ГОСТ 13109-97 to quality of electric power and forestaling of emergency situations in the system of power supply. First got analytical expressions of functional dependence between the measureable rejection of tension, power-factor and values of parameters of electro-consumers. The method of construction of border values of parameters of electrical engineering devices of the system of power supply, qualificatory her static stability for the case of linear dependence of coefficients of characteristic polynomial from the sought after parameters, is first worked out. Solvency of methods is confirmed by experimental researches.
