摘要
为了对高压变电站内因开关操作而产生的空间瞬态电场进行有效的测量 ,研制了一套光纤瞬态电场传感器。采用球形探头将空间瞬态电场变换为瞬态电压 ,由置于探头内部的微型光发射机通过光纤把瞬态电压信号传输到远端的光接收机 ,解决了强电磁干扰环境内的瞬态电场的测量问题。
In order to measure the transient electric field due to switching operations in high voltage substations,an optical fiber sensor is developed.A spherical probe is used to transform the transient electric field to transient voltage,and the sensing signal is transmitted to the receiver via an optical fiber link.The results of the testing in laboratory and measuring in substation show that the specifications of the sensor satisfy the requirements for measuring the transient electric field in substations.
