Highly efficient power transmission meets huge energy demands  Expertise and experience at Siemens Energy produce superior transformers in different HVDC schemes like HVDC Classic and HVDC Plus. HVDC converter transformers are indispensable, where highly efficient bulk power transmission for offshore and onshore grid connections is neccessary. Transformers are the important link within the energy value chain towards achieving a successful energy transition. Today, the energy landscape is changing rapidly, and our customers need to respond flexibly to power fluctuations due to renewable energy generation. Therefore, the requirements for power dissipation and continuous and reliable power transmission are higher than ever. At the lead center in Nuremberg we pool an extensive know-how and make sure that the same technology and quality are available to our customers around the world, while two additional HVDC facilities in China and Brazil can keep distances for transport to a minimum. Where transmission power capability of HVDC systems is steadily increasing, our customers can rely on our experienced design teams to help master transmission and grid challenges around the globe. As a world-class leader synonymous with top quality and reliability, Siemens Energy enables the successful implementation of HVDC transmission systems with dedicated research and development programs. Designing and building a HVDC transformer is a complex process. The insulation to ground and between line and valve winding has to withstand AC and DC stresses. Valve windings need to be tested with voltages determined by the protection level of the DC side.
