HVDC transformers are key components of HVDC stations. HVDC converter and inverter stations terminate long-distance DC transmission lines or DC sea cables. This type of transformer provides the interface between AC grids and high power rectifiers and are used to control the load flow over the DC transmission lines. These actors adapt the AC grid voltage to an adequate level which is suitable for feeding the valve system of DC converter and inverter. Design options The design concept of HVDC transformers is mainly influenced by the rated voltage, rated power and transportation requirements like dimensions, weight and mode of transportation. Many large power HVDC converter station are located in rural areas of low infrastructure. Frequently, special geometrical profiles have to be fulfilled in order to move such transformers by railway. Typically, HVDC transformers are single phase units containing 2 winding limbs. This concept can include either 2 parallel valve windings (two for delta or two for wye system, fig. 5.8-1) or two different valve windings. In order to reduce the total transportation height frequently the core assembly includes 2 return limbs. Due to redundancy requirements in HVDC stations 3 phase units are quite uncommon. The valve windings are exposed to AC and DC dielectric stress and therefore a special insulation assembly is necessary. Furthermore, special lead systems connecting the turrets and windings have to be installed in order to withstand the DC voltage of rectifier. Additionally, the load current contains harmonic components of considerable energy resulting in highe r losses and increased noise. Above all, special bushings are necessary for the valve side to access upper and lower winding terminals of each system from outside. Conclusively, two identical bushings are installed for star or delta system. For approving the proper design and quality of manufacturing special applied DC and DC polarity reversal tests have to be carried out. The test bay has to be equipped with DC test apparatus accordingly and needs to provide adequate geometry to withstand the DC test voltage. HVDC Transformers react as coupling elements between the connected AC grids and high power rectifiers, and are necessary for adapting the voltage. They insulate the rectifier itself from the AC grid and generate a phase shift. New HVDC applications are seen between existing, well-established networks. A back-to-back link can easily combine two different AC networks together, even with different frequencies. Such solutions can also help customers to strengthen and optimize their networks. The changing environment provides more and more opportunities to HVDC solutions, and Siemens is prepared to provide its customers with either our solution or with converter transformers as a loose component .

Altrazeal® is a patented powder dressing specially engineered to cover and protect the wound and to provide an ideal moist wound healing environment that supports cellular function and tissue repair. Its non-resorbable, sterile granules aggregate when hydrated with saline to form a moist, flexible, oxygen permeable film that fits and seals the wound. The skin-like barrier serves many functions that promote healthy granulation tissue growth: 1. seals and protects the entire wound surface 2. allows oxygen transportation 3. manages exudate through vapor transpiration 4. prevents penetration of exogenous bacteria Altrazeal® enables extended wear time, allowing the wound to heal without disturbing the wound bed with frequent dressing changes.
A transformer is an electrical device which is used to transfer power from one circuit to another through electromagnetic induction. The power transfer is accompanied without frequency change. In an electronic system, the term power transformer is used to provide a number of AC supplies of several voltages and appropriate values of current from the public electricity supply. Tungwell oil immersed transformers are up to 750kV, 1500MVA and cast resindry type transformers are up to 110kV, 40MVA. Our design team has very strong design capabilities and uses a variety of design software including 2D and 3D electrical field FEM and Magnetic flux leakage calculators. The resulting products come with many advanced features such as low loss design, short circuit withstand assurance, reliable extra-high voltage protection with overheating controls. The range of small power transformers can be from500-7500kVA The range of medium power transformers can be from-100MVA The range of large power transformers can be from100MVA & beyond
