The operating value of earth leakage protection can be changed with the mains voltage, but the operating value of cables insulation resistance is held the line.
该设计可以根据电网电压的波动调整动作值，从而保证电缆绝缘电阻的动作值不变；
The result shows, under different vibration mode, equivalent parallel capacitance and resistance are not constant value. There is negative damp effect in transducer system at the operating mode.
结果表明，在换能器不同振动模态下，等效并联电容电阻并非恒定值，而且实际支承工况下换能器系统工作时存在负阻尼效应。
