摘要
分布式光纤温度传感器（ＦＯＤＴ ｓｅｎｓｏｒ）用于地下电力电缆故障检测，可对阻性接地系统故障进行快速定位。最大可测距离为１０ｋｍ ，定位精度为１ｍ 。
In fault locating of XLPE insulated underground cable of resistance grounding system, the fiber optic distributed temperature sensor (FODT sensor) can be used to locate the fault position quickly. The maximum measurable distance of this sensor is 10km, its location accuracy is about 1m, and the time for the location of fault position is 30 second.
