An optical current sensor (OCS) for distributed current measurements on high-voltage direct current (HVDC) networks is presented in this paper. The sensor prototype, comprising a piezoelectric transducer and a fiber Bragg grating (FBG) as a principal optical strain sensing element, is evaluated through laboratory testing and its performance is assessed within the context of the accuracy requirements specified by the relevant industry standards. It is demonstrated that the device has the potential to meet the requirements of the accuracy class 1 specified by the IEC 61869-14 standard.
