A frequency sensitive detector controls a saturable reactor to vary an artificial electrical load on an alternator to maintain its speed constant with variations in the normal load. The alternator may be driven by a water turbine and supply a normal load of up to 5 KW. As described the frequency sensitive element is a parallel tuned resonant circuit. |
