Lightning impulse withstand tests for optical fiber current sensor with external conversion

摘要

A prototype of the optical fiber current sensor with external conversion has been developed at the Department of Optoelectronics of Silesian University of Technology. The prototype which has been extensively tested will be applied to measure electric currents at voltages of magnitude 30 kV. Therefore, voltage strength tests were carried out as part of this work. The results presented in this work show good insulating properties of the tested prototype sensor. Our studies also allowed determination of the impact of lightning impulses on the metrological properties of the sensor.
