Abstract
A preferred embodiment of a power-generating device for use in drilling operations comprises a turbine comprising a housing, and a rotor assembly rotatably coupled to the housing so that the rotor assembly rotates in response to the passage of drilling mud therethrough. The power-generating device also comprises one of an alternator and a generator assembly comprising a magnet, a winding, and a housing. The power-generating device further comprises one or more wires for transmitting electrical signals between a first and a second electrical component by way of the power-generating device. The one or more wires are routed through the housing of the turbine and the housing of the one of an alternator and a generator.
