Oil voltage transformers NKF type, 110-500kV

NKF type voltage transformers – single-phase, electromagnetic, oil, outdoor installation, designed for large-scale conversion of alternating voltage with a view to further measurement and supply to the inputs of the measuring equipment, protection and alarm device.

The voltage transformers are cascaded, 66, 110 and 132 kV voltage classes are single-block, 150, 220 and 330 kV are double-block, and 400 and 500 kV are three-block.

Each transformer unit has its active part and windings with electrostatic screens. The active part is placed on a porcelain tire filled with transformer oil.
