By anti-seismic calculation of one type of 1 100 k V transformer bushing(Type A)
it reveals the arc area stress is bigger than it in straight line area
and this is verified in anti-seismic test of another type of 1 100 k V transformer bushing(Type B). Therefore
it is not accurate to take root-section area stress to determine whether the seismic test is pass or not. It needs further discussion to how to judge the seismic test is pass or not.
