from 5.41 g/cm3 to 5.24 g/cm3. With this base, the influence of varistor capacitance and high voltage gradient were scrutinized and it led an improved transition speed of the varistor assembly from non... operation depends on the steepness of the incoming transients [7, 9]. This shows the fact that the high steep transients do not allow the capacitance to disappear quickly and result in a delay......
