Through deduction and analysis, the conclusion can be made: low reactance at the neutral point of transformer has little effect on the switching over-voltage in power systems.

通过计算和分析表明：变压器中性点接入小电抗对系统的操作过电压基本不会产生影响。

Hot switching may be required when the interval from when power is applied to the point when the measurement is made must be closely controlled.

当必须严格控制从施加电压到进行测量之间的时间间隔时，就需要采用热切换。

Mr Thompson said being able to build up to 12 nm offshore made it "more acceptable" from a visual point of view and made more wind power available.

The point is -- the point I made clear is that he will take every action he can within his power, and to order that action taken, in this case, required a presidential memorandum.
