Reich, Klemens; Weissnar, R.; Puffer, Ralf Investigation of the dynamic rating of tubular busbars in substations
Based on the thermal results, the authors calculate the dynamic stability of the EIPB (enclosed isolated phase busbar) to analyze the electrodynamic force under short circuit conditions .
In many instances HV outdoor substations with a high current rating are constructed more economically with aluminium tubular busbars rather than with stranded conductors.
3.2 Multi-Field Experimental Verification Through short-circuit impact tests, thermal cycling, and vibration testing, the deformation, contact stability, and temperature rise of copper busbars can be evaluated

Home Publications Investigation on the dynamic rating of tubular busbars in substations Session Materials Investigation on the dynamic rating of tubular busbars in substations Ref B3
This paper presents a thermal model that can be used to calculate both the steady-state and transient electrical current carrying capacity (ampacity) of a power system busbar.
The higher current loading of overhead lines also increases the current loading in substations. In some cases busbars appear to be the new limiting element. As weather-dependent operation of tubular
