.... A tidal current turbine reacts almost instantaneously to the velocity variations, because the inertia of the turbine is small compared to the inertia of the water flow crossing the rotor. This results in power fluctuations of a single turbine, at least as long as the water velocity does not exceeds...

... parts. The construction of vane or in our case roller type motors are as the Moyneau motor, simple devices. However due to the somewhat ‘interfering’ fit between rotor and stator, Moyneau motors are somewhat difficult to take apart in particular when one also takes the greater length and weight...

... ABSTRACT This paper presents an on-line current monitoring system for detecting rotor faults in large high voltage 3-phase induction motors. The philosophy and practical advantages of current monitoring are discussed and samples of on-site case histories will verify the effectiveness...
