A dry type HV insulation system for extreme environments

Sa？etak The aim of this article is to make readers aware of a dry type, paperless insulation technology that offers a safer and cost-effective alternative to traditional oil-filled current transformers. The design concepts and advantages of this unique HV dry type current transformer technology have been delivering verifiable improvements to the power grid over the past 20 years from 35 kV to 600 kV. The example of the implementation of this technology in Canada is a good case in point. Multiple evolutions of the technology have been continuously expanding its application from HV to UHV operation. Furthermore, the addition of a built-in insulation condition monitoring system completes the safety and sturdiness of the platform
