SF6 Voltage Transformers of the НOГ series

Measuring voltage transformers with SF6 insulation НОГ(NOG) are intended for use in alternating current circuits with a frequency of 50 or 60 Hz in order to transmit a signal of measuring information to measuring, protection, automation, signaling and control devices. The transformers are filled with SF6 gas and have a pressure monitor with a signaling device. At the request of the customer, the transformers can be equipped with an SF6 gas density sensor with a high and low SF6 pressure level indicator. Our plant produces the following НОГ(NOG) transformers: НОГ-123 (НОГ-110), НОГ-145 (НОГ-132), НОГ-170 (НОГ-150), НОГ-245 (НОГ-220)



SF6 Voltage Transformers of the НКГ series

   Gas-insulated measuring voltage transformers НКГ(NKG) are designed for use in alternating current circuits with a frequency of 50 or 60 Hz in order to transmit a signal of measuring information to measuring, protection, automation, signaling and control devices. Transformers are gas-filled explosion-proof products. The NKG transformer of the support type consists of two blocks. The upper unit is mounted on the flange of the lower unit and is mechanically and electrically connected. The gas with which the transformer is filled can move from one unit to another. Each block is a polymer cover on a metal base. The active part of the transformer is a double-rod magnetic circuit with windings on each rod. On the lower core of the magnetic circuit of the lower block, there are two or three secondary windings - one or two main and one additional. Our plant produces the following НКГ(NKG) transformers:

НКГ-362 (НКГ-330), НКГ-525 (НКГ-500).
