description Purpose. The aim of this study is to obtain a method for determining the capacity surge arrester nonlinear absorb energy without breaking the heat balance in modes of long-term application of operating voltage, which allows for analysis of their work in terms of violations as electricity. Methodology. For values of the energy passing through the arrester must be able to determine the current value for the voltage value in the area of leakage current-voltage characteristics. We have carried out calculations of the energy passing everywhere arrester for certain periods of time based on the current-voltage characteristics obtained experimentally. Analysis of the experimental current-voltage characteristics of resistors and literature led to the important conclusion that the dielectric properties of the ceramic varistor affect the value of active power losses in the arrester only when the active component of the leakage current is very small. This is confirmed by the characteristics of different classes of varistor voltage. This property of varistors and surge arresters shows the need to consider how the dielectric and conductive properties of the varistor ceramics in the analysis of work in the area of the arrester leakage current-voltage characteristic. These results demonstrate the need to clarify the mathematical model and the method for determining the energy dissipates in the area of the arrester leakage current CVC with their account. Results. The study, an improved mathematical model for calculating energy affects surge arrester during its working life. The study obtained the method, of evaluation capacity surge arrester, maintains heat balance throughout working life. Based on experimentally obtained current-voltage characteristic of the varistors is defined voltage at which surge arrester starts conducting active current. This allowed to receive specified mathematical model for calculating energy affects surge arrester and develop a method of evaluation capacity surge arrester maintain heat balance throughout working life.

На основе экспериментально полученных вольтамперных характеристик варисторов определено напряжение, при котором ограничитель перенапряжений нелинейный (ОПН) начинает проводить активный ток, что позволило получить уточненную математическую модель для расчета энергии, которая действует на ОПН и разработать метод оценки способности ОПН поддерживать тепловой баланс на протяжении всего срока эксплуатации. На основі експериментально отриманих вольтамперних характеристик варисторів визначена напруга при якій обмежувач перенапруг нелінійний (ОПН) починає проводити активний струм, що дозволило отримати уточнену математичну модель для розрахунку енергії, що впливає на ОПН та розробити метод оцінювання спроможності ОПН підтримувати тепловий баланс на протязі всього строку експлуатації.
