Yes, the power indicator was on, but the video wouldn't play. Might the voltage is too low.

检查过了，指示灯亮着，但录像机不工作，可能是电压太低了。

With the proportion increasing of wind power generation in power grid, the power grid demand for increasingly high to wind turbine. Low-voltage through technology (LVRT) is one important indicator.

随着风力发电在电网中的比例日益增加，电网对风电机组的要求也越来越高，低电压穿越技术(LVRT)就是其中一项重要指标。
