With a typical fault analysis about the produce mechanism of resonanceover-voltage, some practical restrain measures are put forward.
以一起典型事故分析谐振过电压的产生机理，并提出一些具体实际的抑制措施。

Also the capacitance divider has the possibility of resonance with inductance component in the system, which can make a heavy over-voltage and endanger the running of equipments and power system.
