Abstract
The turbine (100) can be used to transmit electrical data signals, for example, sensor data signals, across a down hole turbine using, with the data signals be communicated via a shaft (102). As a result, a signal can be induced onto the shaft (102) from a lower end of the shaft (102), for example, motor shaft, to an upper end of the shaft (102). The signal can be induced on the shaft (102) by a first induction loop (112) and can be picked up by a second induction loop (114) with the first induction loop (112) being downhole from the second induction loop (114). The second induction loop (114) can be communicatively coupled to a receiver (712) which can pass the signals passed to a transmitter (712), for example, a measurement while drilling (MWD) unit. The MWD unit can then process the signal and transmit the signal to the surface.
