The DNEE is an electronic voltage transformer with a capacitive divider, an instrument transformer family covering network designations of 35, 110, 220, 330 and 500 — the full span from regional distribution through extra-high-voltage transmission. Unlike conventional electromagnetic voltage transformers, the electronic capacitive-divider architecture supports digital substation integration, with output conforming to the IEC 61850-9-2 process bus standard that defines modern sampled-value substation communication.
The product line offers accuracy class options of 0.1, 0.2, 0.5, 1.0 and 3.0, covering revenue metering at the precise end through protection duties at the broader end, and is supplied in column configuration with protection class options including 3R and 6P. Digital substations are the declared modernization direction of grid operators worldwide, and IEC 61850-9-2 compliant instrument transformers are the enabling hardware of that transition.
Russian high-voltage apparatus manufacturing serves one of the world's largest transmission grids, and equipment from this base operates across the CIS, Asia and beyond. At prices from 9,000 USD with single-unit minimum order, the DNEE addresses grid operators, substation EPC contractors and electrical equipment importers executing digital substation projects at significantly lower capital cost than Western instrument transformer suppliers.
