Homepage HV Transformers, Detection Systems, and Transformers Current transformers HV in paper-oil insulation from 72.5kV to 765kV

High-voltage current transformer in paper-oil insulation (72.5–765 kV)

Application

High accuracy class (0.1/0.15) and ideal frequency response distinguish paper-oil insulated HV current transformers from other available solutions. This is also what makes them ideal for use at measurement points, in high-voltage line and substation protection, and in HVDC projects. Explore our range of HV transformers designed to handle primary currents from 1–5000 A and operating voltages from 72.5–765 kV and manufactured in accordance with relevant standards.

Thanks to their robust construction, paper-oil-insulated current transformers can operate in extreme weather conditions. They perform reliably at altitudes above 1000 m, in seismically active areas, and in high-wind environments. We offer a wide range of terminals, cable glands, and accessories for these products.
