a Effect of water salinity on the peak value of the current. Error bars indicate standard deviations, with all values ≤0.53. b Influence of an obstacle on the current signals. c Comparison between the received current signals in clean water and those in turbid water. d Schematic diagram of the drilling platform with oil pipeline. e Variation of the peak value of short-circuit current output transmitted in a water pipe of 100 meters. Tr and Re represent transmitting and receiving electrodes respectively. v is the liquid flowing speed. Error bars indicate standard deviations, with all values ≤0.46. f Comparison between the short-circuit current signals transmitted in a straight and those in a curved water pipe.
