We demonstrate experimentally for the first time an all-optical in-fibre differential current unit protection scheme utilising hybrid fibre-optic current and voltage sensors. The prototype system does not require a secondary communications channel and can interrogate up to 30 separate transducers for current and temperature at kHz rates. The scheme is shown to perform well over a range of internal and external faults indicating its ability to implement future novel protection schemes, discussed herein.
