对于中性点不直接接地的发电机，由于三相对地电容值存在差异，中性点与地之间存在一定电压。
Due to three-phase capacitance to ground, certain voltage exists between the neutral and the ground for a generator with ungrounded neutral.
相对于中性点非直接接地系统而言，发生在中性点直接接地系统中的铁磁谐振过电压有着许多新的特点，而且对它的研究相对较少。
Compared with neutral ungrounded power system, ferroresonance overvoltage occurred in neutral grounded power system has more new features, and the research about it is much.
