Abstract
The article describes a model that takes into account the impact of unauthorised modes of power transformers owned by consumers on the efficiency of the distribution system operator's power grids. A mathematical model for analysing electricity consumption in power transformers has been developed using real electricity consumption schedules of energy cooperatives and the magnitude of possible abuse is indicated in the case of monthly electricity metering. The influence of unauthorised replacement of transformers on the value of active and reactive power consumption in this transformer is investigated. The article substantiates the limits of daily electricity consumption by an energy cooperative when the actual transformer losses exceed the normalised transformer losses obtained by the calculation method in accordance with the SOU-N EE 40.1-37471933-82_2013. The expediency of reconstruction of metering systems for hourly analysis of electricity consumption is substantiated. Bibl. 14, fig. 4.
