«RelavExpo» is a key industry event that has been held biennially since 2012. It brings together major players in the electric power market and serves as a central platform for professional dialogue and technological exchange. In 2025, over 3,000 participants from leading Russian enterprises took part in the event.
This year’s exhibition and conference were organized by the Electrical Engineering Cluster of the Chuvash Republic, PJSC «Rosseti», and the Ministry of Industry and Energy of the Chuvash Republic, with support from the Ministry of Energy of the Russian Federation. The participation of representatives from the Ministry of Energy, Ministry of Industry and Trade, PJSC «Rosseti», JSC «Rosatom», and PJSC «RusHydro» underscored the high status and national importance of RelavExpo.
The Association “Innovative Territorial Electrical Engineering Cluster of the Chuvash Republic,” one of the event's co-organizers, plays a key role in bringing together market leaders, customer representatives, as well as students and faculty members from specialized technical universities. The welcoming atmosphere and outstanding organization were felt throughout the engaging and dynamic RelavExpo program. Many professionals in relay protection and automation are eager to attend this event, which sets scientific and engineering trends, facilitates knowledge sharing, and promotes professional development.
The main theme of RelavExpo-2025 focused on the digitalization and technological sovereignty of Russia’s electric power industry. S.V. Chekunkov, Head of the «Power Line Communication Equipment and Reactor Department», presented a report titled “Experience in Implementing Projects Using Line Traps by JSC NPP EIS.” The report summarized many years of development aimed at enhancing line trap design and implementation.
