THE PURPOSE. To determine the number of reconstructed, newly installed and replaced 10 / 0.4 kV transformer substations, consider an improved technology for installing a "pillow" under the foundation of a kiosk-type 10 / 0.4 kV transformer substation and determine the time spent on its installation. METHODS. The article presents an analysis of data on the number of reconstructed, newly installed and replaced 10 / 0.4 kV transformer substations, an algorithm for installing an improved "pillow" under the foundation of a 10 / 0.4 kV kiosk-type transformer substation. RESULTS. In the course of the experiment on the installation of an improved "pillow" under the foundation of the CTS, the time of work was determined. The total time spent on the construction of an improved "pillow" under the foundation of a kiosk-type CTS was 580 minutes, which is just over 9.5 hours. Also the standardized time of work during the installation of an improved "pillow" under the foundation of a kiosk-type CTS Also, the standardized time for performing work during the installation of an improved "pillow" under the foundation of a kiosk- type package transformer substation has been proposed. CONCLUSIONS. The use of the data presented in the article on the number of reconstructed, newly installed and replaced 10 / 0.4 kV transformer substations will allow scientists and specialists to develop and propose new methods of reconstruction and construction technologies for various transformer substations, as well as determine the economic efficiency of new foundations for transformer substations. The technology of kiosk-type CTS foundation installation described in the article will allow not only to increase the operational characteristics of the CTS, but also ensure the fire safety of the installed equipment. The technical solution specified in the article can be used during the reconstruction and construction of a 10 / 0.4 kV kiosk-type package transformer substation. The proposed algorithm for mounting an improved "pillow" under the foundation of a kiosk-type package transformer substation is universal, since it can be used at a package transformer substation of various capacities.
