“…Different methods can be employed to calculate the forces, e.g., the empirical method, the image current method, the complex vector potential method, and numerical methods. The empirical method has been used to evaluate the forces by certain companies and researchers (Willson & Mankoff, 1954;Skeats & Swerdlow, 1963). This method uses a scaled-down experimental system and is very costly and difficult.…”

Short-circuit electromagnetic forces have a vital role in the mechanical design of isolated phase buses. Electromagnetic forces in isolated phase buses under short-circuit conditions are analyzed in this article. These forces are calculated using the time-stepping finite-element method. The effects of system dimensions and material properties on the maximum value of forces and the time of its occurrence are investigated through extensive simulation. The concluding remarks are useful for the design and protection of the buses.

Short circuit electromagnetic forces have vital role in the design of isolated phase buses. Therefore, accurate determination of these forces is needed. In this paper these forces as well as eddy currents and magnetic fields are calculated using finite element method. A program is then developed to find the worst conditions at which maximum short circuit electromagnetic forces occur. The results are discussed and conclusions are drawn for design purposes.Index Terms--Isolated phase bus, Electromagnetic force, Magnetic field, Finite element method.

“…To achieve that, bus thermal analysis, highest temperature rise and temperature distribution need to be done. Many professors did research on thermal analysis using analytical method, thermal network method and finite element method (FEM) [5][6][7] . Till now, FEM has a higher accuracy and the capacity of thermal-force coupling analysis [8][9] .…”

In the design and analysis of Non Segregated Phase Bus (NSPB), steady temperature rise calculation is very important especially for the bolt-joint contact structure NSPB. In order to ensure the safety of such products, taking a certain type of NSPB for example, finite element method (FEM) calculation model of NSPB is built based on thermal transfer theory, the maximum temperature rise of NSPB is calculated under different DC and AC loads within the bus working range, the temperature distribution of contact area is simulated; and the temperature correspondence relationship of DC-AC is discussed; the NSPB temperature rise has been tested and compared with the experiment results, the validity of NSPB FEM calculation is verified.
