  • Abstract
    A new technique to obtain reliable and noise free signals proportional to the acceleration and to the deviation of the rotor angular velocity of a generator from the system synchronous angular velocity was implemented and tested. The signals thus obtained had considerably higher signal-to-noise ratio compared to the signals derived from a conventional tachometer (about 30 to 50 dB improvement) with the same bandwidth.
