Three-Phase Anti-Resonance Voltage Transformer Group for Electrical Distribution Applications

Three-phase anti-resonance groups are designed for installation in complete switchgear (switchgear) or closed switchgear (closed switchgear) and are used to supply electrical measuring devices, protection and signalling circuits in electrical installations of alternating current frequency of 50 or 60 Hz. They are resistant to ferroresonance and (or) to the effect of intermittent arcing in case of earth fault of one of the network phases. Three-phase anti-resonance groups are manufactured in climatic version "U" or "T" of placement category 3 for 3xZNOL.06 and placement category 2 for 3xZNOLP according to GOST 15150.
