To solve this problem, the Selnikovo substation was chosen, located in the service area of the eastern branch of the company. The project partner was Tavrida Electric Group of Companies. As of today, the specialists have installed new equipment: installed two SMART35 reclosers with an automatic line reserve switching device in the Dedinovo – Selnikovo and Selnikovo – Twin II with tap lines. The design of the installed SMART35 reclosers includes a built-in measurement system, microprocessor-based relay protection devices, sensitive protection against single-phase earth faults, logic protection, as well as telecommunication interfaces for local and remote control. An important feature is the fact that the device is programmed and tested taking into account the specifics of its installation and further use. The recloser is equipped with the world's smallest 35 kV vacuum interrupter. The body of the SMART35 recloser is covered with silicone rubber insulation, which is highly resistant to environmental influences. The recloser control device, providing high speed of information processing, has minimal dimensions and power consumption. The equipment does not require special maintenance and preventive maintenance throughout the entire service life, due to the high reliability of the structure, the use of external insulation made of silicone rubber (it has greater resistance to significant temperature drops and better electrical insulating properties in comparison with other types of insulation), the absence of a large number of moving parts and high stability of factory adjustments. The uniqueness of the dimensions of the device, the ability to install in vertical and horizontal positions, the functionality of protection and automation, ease of integration into dispatch control systems allow using SMART35 in almost all sections of the network. According to the Deputy Director - Chief Engineer of the Eastern Electric Grids of PJSC "MOESK" Alexander Yurtaev, sectioning devices have already proven their effectiveness in distribution networks, on 6-10 kV power equipment. For the first time, reclosers were installed on high voltage equipment of PJSC "MOESK". Power engineers expect that the use of new, modern equipment in the 35 kV voltage class will significantly improve the reliability and quality of power supply to consumers. © 2015 "Tavrida Electric"
