DC voltage measurement device is the key equipment in the DC transmission system, which is mainly used for system voltage measurement and providing voltage signals to the measuring instruments and secondary protection devices. With the rapid development of DC transmission and flexible transmission in China, DC voltage measurement device has been widely used and developed. High accuracy and high stability...
Taking an instrument in transformer winding distortion measurement as an example, a solution is proposed based on Samsung's S3C2410 processor and embedded Linux operating system Hardware design is introduced, and software design also is described. The application of the artificial neural network technique to the frequency response analysis method (FRA) which is used to detect transformer winding deformation...
The flow stress is one of the most essential parameters that reflect the capability of a material in plastic deformation. It is also an important factor that affects the precision of finite element (FE) simulation. However, recent research on material flow stress has focused mainly on cold and hot forging: as to warm forging, little research has been done on this aspect. With the gradually widening...
