摘要： Embodiments provide an integrated motor-compressor assembly including a rotating impeller to compress a fluid passing therethrough, and diffuser vanes radially spaced from the impeller, each of the diffuser vanes including a stator winding therearound, the stator windings being supplied with current to generate sufficient magnetic flux for rotating the impeller. Embodiments provide an integrated motor-compressor assembly including a volute casing housing a rotating impeller to compress a fluid passing therethrough, a stator fixedly positioned in the volute casing proximate to the impeller, the stator including stator poles axially spaced from the impeller, each of the stator poles including a stator winding, the stator windings being supplied with current to generate sufficient axial magnetic flux for rotating the impeller.

摘要： A failure detection system for an energy network includes a radio frequency (RF) receiver adapted to be coupled with or in close proximity to the energy network, the RF receiver providing an amplitude modulated RF signal; an RF amplifier receiving the amplitude modulated RF signal and providing an amplified signal; an envelope detector receiving the amplitude modulated RF signal and providing a demodulated envelope signal; an optional algorithm implementation system receiving the demodulated envelope signal, where the optional algorithm implementation system processes the demodulated envelope signal by one or more of a Fast Fourier transform (FFT) trigger system and a phase-locked loop (PLL) trigger system; and a signature output that is the overall output signal of the failure detection system, wherein the signature output is adapted to indicate whether the energy network is experiencing partial discharge.

摘要： A smart sensor network for power grid health monitoring includes a plurality of spaced sensors that are magnetically coupled to the power transmission line to be monitored. The sensors include a signal injection unit and a signal sensing unit. As such, one of the sensors acts to inject, via its signal injection unit, a high frequency signal through the magnetic coupling into the power transmission line, while sensors on either side of the signal injecting sensor act to block the injected signal, which is then detected by the signal sensing unit of the injecting sensor, and is used to measure the impedance of the power transmission line segment being analyzed. Based on the difference between a pre-measured impedance of the power transmission line being monitored and the actual impedance value of the power transmission line being measured by the sensor, the health of the power line can be obtained.

摘要： System and method for monitoring the condition of electricity conductor support systems, i.e. towers, in a power network distribution system employing a tower structure integrity sensor assemblage. The system allows for identifying particular portions of a structural system for maintenance attention. The tower sensors allow identification of structural failures of electricity transmission towers.
