Question

求英语高手翻译下下面一段话

The nominal electric supply voltage from DEWA is 220/380V +10%, 50 Hz, 3- Phase, 4-
Wire with separate neutral and protective conductor (generally metallic covering of the
cable supplying the installations). The neutral is solidly earthed at DEWA's substations
and shall not normally be earthed elsewhere in the electrical installations. The design fault
level within the substation is 40kA (fault duration – 1 Sec), except for fuse protected
equipment/circuit.
The normal voltage of existing 220/380V system shall evolve towards the IEC
recommended value of 230/400V + 10% (IEC.38) before the year 2005.
从上面的内容中是不是可以得出：2014年现在采用的电源电压是230 / 400V + 10%？？

XXL PornTube(20)电缆提供安装)。中性是坚实DEWA变电站的接地通常,不得被接地的电气安装的其他地方。设计错误水平在变电站40 ka(故障持续时间1秒),除了保险丝保护
设备/电路。现有的普通的正常电压对独立选举委员会制度的发展推荐值230/400V + 10%(IEC.38)在2005年之前。
希望能帮到你，求采纳O(∩_∩)O~

Answer 2

从德瓦标称电源电压为220 / 380V + 10%，50赫兹，3相，4线分开的中性和保护导体（通常为金属覆盖的电缆供电装置）。中性接地在德瓦的变电站和通常不应被其他电气设备的接地。在变电站设计故障程度的电流（故障持续时间–1秒），除了保险丝保护设备或电路。现有的220 / 380V系统正常电压应朝着IEC 230 / 400V + 10%的推荐值（IEC。38）前2005年。
