Almost all electricity is generated from the electricity grid. The main function of the power system is to supply electricity to consumers, that is, to transfer electricity from the place where it is generated to the place of its use. An improved understanding of the transmission and distribution of energy is the power system. The power system is a collection of power plants that are interconnected by these transmission lines and together provide electricity to consumers, the research results are presented [1]. electricity, current, power dissipation, control, voltage. Introduction To heat the waste of electricity, a principled electrical scheme is used [2]. Normally, the hbee supply center in this mode is the installation points, the type of reactors, the brand, the cutting surface and the length of the cable and havo lines tarmoq and subscriber transformer nimstans. At the transformer station, the cache name, the data of power transformers, and the data of the switch siya apparatus should die. At the center of the taste and at the ta qsimulation points, the name of the line for simulating and supplying the name of the section should be specified in these sections [3]. In addition,in the q bee scattering scheme, the electrical grid is equipped with token separators in accordance with it in normal operating mode. The calculation of the waste of electricity used the exact values obtained from the automated control and computing system, and if there is no system, the results of the monitoring measurements in the computing period is calculated . 10(6) Determination of electricity waste in power transformers with a power of 0.4 kV.
