Engineering
In Virginia Transformer Corp (VTC), every transformer is custom designed and manufactured based on customer’s Specs and requirements. The guiding philosophy for design is to provide reliability of the product and making a value proposition by working with the customers by sharing our knowledge and experience.
VTC has the unique privilege and capability to serve both Industrial and Utility markets. Within these, there are several product specializations depending on the applications. |

VTC has extensive experience in designing transformers to comply with applicable product standards
Engineering in VTC is organized according to the functionalities, such as Electrical, Mechanical, Control schematics, R& D, Systems & procedures, etc. Each of the manufacturing locations have their own engineering teams, centrally coordinated by corporate engineering. VTC is very proud of the large number of years of experience of our engineers. VTC has a well-developed system of training, so all the engineers learn the design and manufacturing practices of the plants in USA. In addition, VTC has a design office in Mumbai (Bombay), India. Together that gives us capability to design in Metric, English and dual-dimension drawings and other languages like Spanish and French.
The choice of windings and the performance of the transformer are reviewed through use of sophisticated computer programs such as Magnetic and Electric field mapping, Impulse voltage distribution, Force calculations, etc. Circular coils are used for all transformers above a certain KVA and for all critical applications, thus providing higher short-circuit strength. A large number of our transformers have been successfully tested for short-circuits in third- party labs. High quality grain-oriented steel is used for making the cores, using the Step-lap and Miter-cuts, employing our own core-cutting machines in each of the three manufacturing locations.
In order to make the best use of experience of our designers and to gain efficiency through computers, VTC has adopted the philosophy of Interactive automation. For mechanical designs, VTC has switched over to designing in 3-dimensions, which offers very good visualization of the product even before it is built. Further streamlining and integration is under works to achieve the next higher level of efficiency to serve our customers better.
