Kharkov 2015. Dissertation is devoted to actual scientific and technical problem of determining the effect of the higher harmonics of the voltage on the selection and exploitation of surge arresters for protection electricity supply systems is important and enhances the efficiency and reliability of power supply systems. In this area, the following results. The analysis of existing requirements for the selection and exploitation of surge arresters in electricity supply systems of different voltage classes. Experimental studies of electrophysical characteristics of varistors and surge arresters assembled the world's leading manufacturers in the different frequencies of the applied voltage and current voltage characteristics of varistors and surge arresters in an assembled state in the area of leakage current. Іmproved the mathematical model for selecting the energy characteristics of the arrester at a low power quality in the power supply system on the basis of equivalent circuits in the area of the arrester leakage current of the current-voltage characteristics (CVC). Offered the method for determination of active power losses in the arrester on the basis of the obtained current-voltage characteristics in the area of leakage current and the analysis of the impact of non-sinusoidal voltage to the amount of energy exerted on surge arresters, as well as determined the effect of the normal operation of surge arresters Surge lightning and switching current pulses and high frequency voltage. Developed the methods for determining the current-voltage characteristics in the area of the arrester leakage current on the basis of the experimental CVC arresters based on neural networks and approximation CVC two curves of the first order.
