A fluid coupling (140) for transmitting an electric current through a swivel joint is disclosed. The fluid coupling comprises: a housing (124) comprising an outer conductor (148) and an outer insulator (146) arranged between the housing (124) and the outer conductor (148); a shaft (122) comprising an inner conductor (144) and an inner insulator (142) arranged between the shaft (122) and the inner conductor (142); a first seal (160) arranged between the housing (124) and the shaft (122); a second seal (162) arranged between the housing (124) and the shaft (122); a first electrical wire (170) connected to the outer conductor (148); and a second electrical wire (172) connected to the inner conductor (144). a third electrical wire (174) which is connected to the housing (124);a chamber (150) defined at least partially by the inner and outer conductors (144, 148) and the first and second seals (160, 162); and an electrically conductive fluid (152) within the chamber (150) forming an electrical connection between the inner and outer conductors (144, 148).
