In this article, EMS will compute the Lorentz force of a low-voltage busbar system during a short-circuit scenario, comparing the results with analytical solutions.
First, modal analysis is used to calculate the vibration modes and natural frequencies of the busbar systems. The influence of span length and phase-to-phase distance is discussed and thresholds for
If the vibration frequency corresponds to a natural frequency for all conductors, resonance phenomena may occur. In this case the resulting stresses in the conductors may be far greater than those
To explore the vibration response of the GIS busbar enclosure in a strong electric field, the electric force on the busbar enclosure was solved by the voltage in the circuit and the principle of virtual work. The
In the simulation section, the physical phenomenon of electrodynamic forces is being captured by employing a detailed real-scale model of switchgear and current paths.
