The NAMI series voltage transformer is a single-phase three-winding instrument transformer designed for installation in indoor and outdoor switchgear of 3-35 kV networks. It provides voltage scaling for protection relays, metering equipment, and signalling circuits.
Used in transformer substations and distribution networks at industrial enterprises, in power-utility installations, and in railway power-supply systems. Suitable for both grounded and ungrounded networks.
Oil-immersed design with anti-resonant windings; the secondary winding provides power for metering circuits while the additional (auxiliary) winding feeds insulation-monitoring devices. Manufactured in accordance with GOST IEC 61869.
