用于绝缘子串泄漏电流测量的光纤电流传感器
Optical Fiber Current Sensor for Leakage Current Measurement of Insulator String
摘要
Abstract
For the problem of electromagnetic interference when measuring the leakage current of insulator string, this paper makes use of photoelectric conversion and light signal stability and proposes an optical fiber current sensor to measure leakage current of the insulator string, in which the light emitting diode (LED) is used to detect the current signal and the output performance of the sensor is also analyzed. The experiment results show that the optical fiber current sensor can meet the basic requirements of the leakage current measurement to achieve selective measurement of leakage current, the positive half cycle or negative half cycle, and has the advantages of strong anti梚nterference, well linearity and accuracy.关键词
