When the neutral point of the grid is not solidly grounded, the phase-to-ground voltage of the singly grounded phase is zero, while the phase-to-ground voltage of the other two phases increases to \u221a3 times. Although the increase in phase voltage does not exceed the designed insulation strength, it leads to an increase in ground capacitance. In the case of single-phase grounding, the capacitance current is three times that of the normal operating phase-to-ground capacitance current."}
