Current transformers HV in paper-oil insulation from 72.5kV to 765kV


HV oil-insulated current transformers are used in cooperation with measuring and protection devices at HV power stations. They are responsible for providing on secondary site current value in the appropriate scale or accuracy class. The internal insulation is a combination of paper and oil. The insulation housing can be porcelain or silicone. The transformers can contain several current cores. They are manufactured in two main types: head transformers and “safety pins” (hairpin type).
