Dynamic measurements of electric and mechanical parameters significantly contribute to overall reliability of hydro-generators. Overstressing of rotor/stator in many different ways may cause deforming of rotor/stator shape/geometry, making the whole generator system prone to failure.
Thanks to rotor Air Gap Sensor this is the first method to allow real time measurements of stator geometry under dynamic conditions. Rotor Magnetic Induction Sensor makes possible monitoring of the generator system functionalities and may crucially contribute to the overall reliability. Fault prevention is now possible and saves cost of major overhauls.
