The core temperature of power cables is a key supervising factor which concerns the operation safety of transmission line. However, direct measurement influences insulation performance due to embedding instruments into the cable. In this paper a measurement method using temperature retrieval is proposed. The finite element models of the cable are established for excavating the implicit relationships...
The ultra fine pitch micro bump became the future trend due to the development of 3D IC. In this research, three-dimensional simulation was employed to examine the temperature distribution in micro SnAg solder bumps. According to the result, the temperature distribution in solder bump of micro bump is nearly uniform. In addition, the hot side is near the substrate side, whereas the cold side is near...
The rotor eccentricity of a large hydro-generator could cause a huge radial magnetic force, known as an unbalanced magnetic pull (UMP), exerting on the rotor. In this paper, Maxwell stress tensor (MST) method is used to compute the UMP based on the 2-D finite-element (FE) calculation, and the accuracy of UMP FE calculations is investigated. This paper presents a new method for the FE calculation of...
