Gas-insulated voltage measuring transformers NKG series are designed for use in AC circuits with a frequency of 50 or 60 Hz in order to transmit the measurement information signal to measuring, protection, automation, alarm and control devices.
Transformers are gas-filled fire and explosion-proof products. Transformer NKG type, consists of two blocks. The upper unit is mounted on the flange of the lower unit and has a mechanical and electrical connection. The gas with which the transformer is filled can move from one unit to another. Each unit is a polymer tire on a metal base.
The active part of the transformer is a two-core magnetic core with windings on each rod. On the lower core of the bottom of the magnetic circuit, there are two or three secondary windings – one or two primary and one additional.
