Power Transformers for HVDC Applications GE is a recognised and trusted partner in the design, manufacturing and commissioning of HVDC converter transformers, with almost half a century of expertise and more than 170 HVDC converter transformers sold worldwide. HVDC Power Transmission Solutions GE is among the top players in the world able to offer HVDC power transformers that are safe, reliable and valued by our customers. References date back to the early 70s when Grid Solutions supplied nine 500 kVdc converter transformers to Manitoba Hydro for their Nelson River transmission project. These transformers have been up and running for more than 37 years, with no reported service failures. Since 2000, GE has supplied Manitoba Hydro with an additional 21 HVDC converter transformers as well as back-to-back or point-to-point transmission solutions for many other utilities worldwide. GE offers two HVDC technologies for LCC (Line-commutated current-sourced converter) and VSC (Voltage-sourced converter) applications. The latter is more commonly used for short distances and lower transmission power. GE has the capacity to absorb strong HVDC market growth from anywhere in the world with state-of-the-art factories and equipment and a production capacity of more than 180,000 MVA per year. The R&D teams support our global developments through intensive internal technology transfers. GE has an active participation in international standards committees with recognised expertise in many fields. Investment in Customervalued Innovations Heavy investments in R&D to extend the product range up to the highest UHVDC levels. In July 2010, Grid Solutions successfully tested a full scale model of an 800 kV UHVDC converter transformer in the Wuhan factory (China), compliant with IEC and Chinese standards. Since 2011, Grid Solutions has been working on a common 1,100 kVdc development project with one of the largest utility companies in the world. GE is also developing dry bushing solutions for UHVDC applications, including the Resin Impregnated Paper (RIP) technology.
