The net result is that a 5% reduction in the voltage more than doubles the life of the bulb, but delivers 20% less light.

综上所述，减少电压5%能使灯泡的使用寿命延长至少2倍，但是其亮度会下降20%。

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。

Main.net's system skips the high-voltage lines, injecting data into the grid further downstream, on medium-voltage (4, 000 to 25, 000 volts) lines.

Local controllers (X-NET) gather this information and deliver to a web-controller via GPRS. The overhead sensors are line powered, and the X-NET Controller can be powered by a low voltage supply or a solar panel.
