High Voltage, EarlyView.ABSTRACT The problem of gas–solid interface charge accumulation is an important reason for distorting the surface electric field and then inducing surface discharge. The temperature gradient distribution formed on the spacer during the operation of a gas‐insulated transmission line (GIL) will aggravate the surface charge accumulation, further ...

High Voltage, EarlyView.ABSTRACT To solve the ion‐flow field of ultrahigh‐voltage direct current (UHVDC) transmission lines under strong‐wind scenarios, the multiple relaxation time lattice Boltzmann method (MRT‐LBM) is adopted. Compared with previous ion‐flow studies predominantly based on the single relaxation time LBM, the MRT‐LBM framework provides improved numerical ...
