They both have the function to reduce the active power losses and improve nodes' voltage level.

这两者都有降低网络有功损耗和提高网络节点电压的功能。

An arc due to an AC signal usually quenches itself as soon as the voltage level passes through zero.

交流(ac)信号产生的电弧通常在电压通过零点时就会自己熄灭。

The driving device with output unit has the same value for the output resistance of different voltage level.

驱动装置结合有输出单元，其对于不同的电压电平的输出电阻具有相同的值。

It takes the least net loss and the best voltage level as the object functions to optimize system reactive power.

系统以网损最小和电压水平最好为目标函数，对系统进行无功优化。

The voltage level and the supply reliability can be greatly improved, thus more economic profit will be obtained.

同时显著改善网压水平与提高供电的可靠性，从而将收到更大的经济效益。
