Single-phase voltage transformers НОМИ type are manufactured for national economy needs and are intended for using in alternating current with 50 Hz frequency electric circuits.

НТАМИ–6 У3, НТАМИ–10 У3 transformers are large-scale converters of alternating current electric tension for the purpose of its subsequent measuring and feeding the measuring devices inputs, signaling system protectors in 50 Hz frequency and rated voltage 6 or 10 kV networks with insulated neutral.

Three-phase voltage transformers НТМ type are manufactured for national economy needs and are intended for large-scale converting alternating current electric tension for the purpose of its subsequent measuring and feeding the protection and signaling devices in circuits with insulated neutral. The transformers are used for accounting, including a commercial one, of electric power in alternating current electrical equipment.
