Abstract
The turbine () 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 (). As a result, a signal can be induced onto the shaft () from a lower end of the shaft (), for example, motor shaft, to an upper end of the shaft (). The signal can be induced on the shaft () by a first induction loop () and can be picked up by a second induction loop () with the first induction loop () being downhole from the second induction loop (). The second induction loop () can be communicatively coupled to a receiver () which can pass the signals passed to a transmitter (), for example, a measurement while drilling (MWD) unit. The MWD unit can then process the signal and transmit the signal to the surface.
