Analysis of neutral grounded via a transition resistor
YU Shui-zhong · Relay · 2001
An analysis on the change of the three-phase to ground voltage and neutral point to ground voltage is done in this paper as the single phase grounded via a transition resistor in neutral indirectly grounded system. The sensitivity of the insulation supervisory system , the range of healthy phase to ground voltage which is greater than 3 multiple phase voltage and its maximum value are analyzed as well.
