とするエンジン駆動型交流発電機の自動緩速装置。In an automatic slowing device for an engine-driven alternator that automatically reduces the rotational speed of the engine and the output voltage of the alternator during no-load conditions, a saturable current transformer is interposed on the output side of the alternator. This saturable current transformer has a secondary winding that detects the load current, and a control that is connected to the output circuit of the generator and automatically adjusts the detection sensitivity by varying the degree of saturation using a control current that corresponds to the output voltage. 1. An automatic slowing device for an engine-driven alternator, comprising a winding.
