LESSON 20

有关电气破坏（electrical damage）

面露难色的王工

There is this sensor that breaks down easily but I don't know why. The manufacturer says too much voltage or electrical current can cause problems.: 经常会有传感器损坏，但是不知道原因。制造商说电压或电流过高会导致问题。

Cindy

Well, there might be a wire that is accidentally touching to a voltage circuit, or it could be a low resistance value, but the cause for something like this is usually surge noise.: 是的。也可以考虑是因为误接触电压电路或者电阻值不足，不过常见原因是浪涌噪声。

Actually, the sensor is placed in an area that is prone to electrical noise. What should I check to prevent similar problems?: 的确，那台传感器就在容易产生电气噪声的位置。
要检查哪些点才能防止再次发生呢？

Cindy

First, you need to find out where the noise is getting in. The usual suspects for entry are places like the power line or the output line of the sensor.: 首先必须确定噪声的入侵路径。噪声有可能入侵的路径往往是电源线路和传感器的输出线路。
