Abstract: Power transformers are known to be the most important part of electrical complexes. The working condition of power transformers ensures the normal operation of electrical equipment at substations and the supply of electricity to consumers. Reliable forecasting and increasing the service life of transformers is a critical task for electrical complexes in the Syrian Arab Republic under economic sanctions from unfriendly states. The purpose of this study is to increase the service life of power transformers using methods for regulating electricity consumption based on leveling the load schedules of transformers 33/11 substation "Kabun-1" (Adra, Syrian Arab Republic). The paper presents an analysis of the power supply system of the industrial zone of Adra. Approximating functions of daily schedules of active power loads of transformers of the Spinning and Weaving Factory (first and second approximation) have been developed. Measures have been developed to regulate electricity consumption from 33/11 kV transformers of the Kabun-1 substation. Determining the coefficient of utilization of the carrying capacity of a quarry dump truck, taking into account the physical and mechanical properties of the rock mass and loading parameters, is one of the urgent tasks of modern mining production.

Key words: service life transformer approximating function load schedule power consumption control
