During the Forum, representatives of IDGC of Volga, PJSC (a member of Rosseti Group of Companies) demonstrated an innovative solution providing enhanced reliability of power supply in the Ecosystem of Innovation Thematic Zone. Designed as a combination of a neutral-forming transformer and an arc-suppressing reactor, this device is a compact high-performance arc-suppressing unit eliminating single phase-to-earth faults and protecting electrical equipment against destructive single phase-to-earth fault currents. As part of implementing R&D program, specialists of IDGC of Volga, PJSC in collaboration with Bresler Research Center, LLC developed and implemented a static dry-type arc-suppressing unit to eliminate single phase-to-earth faults in 6-10 kV networks. The device is known as an ATDS (transformer dry-type arc-suppressing unit) equipped with a quick-response system of automatic current compensation control. Unlike existing continuously-varying arc-suppressing reactors offered by foreign manufacturers, this unit has a single-body and a single magnet core design. A special system based on the principle of direct measurement of free frequency of a zero-phase sequence circuit, with subsequent change of equivalent inductance by means of capacitor bank switching ensures high-speed response and high-accuracy of settings. After successful high-voltage and thermal tests, the ATDS unit has been put into pilot operation at a facility of IDGC of Volga, PJSC. As part of pilot operation of the ATDS unit, specialists studied transient processes during single phase-to-earth faults. Tests included modeling of various network operating conditions, such as metallic single phase-to-earth faults and transient single phase-to-earth faults. Results of tests and studies demonstrated high efficiency of the ATDS dry-type arc-suppressing unit designed to compensate capacitive currents, equipped with a quick-response system of automatic current compensation control. Based on this unit, domestic hi-tech systems for suppression of single phase-to-earth fault currents in 6-10 kV networks will be launched into serial production. Due to a cost competitive advantage of domestic solution compared to similar products offered internationally, this technology can be extensively used at distribution power facilities.
