Electroshield-K° enhances reliability of metering and protection systems at Novovoronezh NPP
Electroshield-K°
Supply
The Kaluga-based plant Electroshield-K° (a member of the NEC Group) has delivered current transformers to the Novovoronezh Nuclear Power Plant named after V.A. Sidorov — a branch of JSC Rosenergoatom, part of State Corporation Rosatom.
The Novovoronezh NPP holds a key place in Russia’s energy history as the country’s first nuclear power plant with VVER-type reactors (water-water energy reactors — pressurized water reactors with light water coolant). It is also the largest power generation facility in Voronezh Oblast, fully meeting the region’s electricity demand and providing district heating to the city of Novovoronezh.
The delivery was carried out within the framework of the plant’s modernisation programme. The supplied transformers are designed to operate reliably under high-load conditions, ensuring precise conversion of primary current into a safe secondary signal compatible with measuring instruments and relay protection systems.
The current transformers have been integrated into the core technological circuits of the power unit. The equipment is used for: accurate electricity metering; enhancing the performance of relay protection systems during fault detection; Industrial monitoring and automation systems. This integration ensures a high degree of operational control, improves the responsiveness of protection mechanisms, and significantly increases the overall reliability of the power plant’s electrical systems.
