The educational 110 kV step-down substation in the scale of 1/10 is intended for material supplementation of educational processes in higher education institutions training power industry specialists. Lack of continuous and unlimited access of students to power facilities as well as absence of an opportunity to carry out any practical activities there results in severe deficiency in practical knowledge and skills among students. To solve this problem operating material models of substations and separate power equipment were created, both as the visual aid and as laboratory unit scaled in size. The actually operating substation in the scale of 1/10 allows performing and practicing a wide range of educational activities such as designing, constructing, installing, routine switching, etc.
