Abstract: Asynchronous generator can work connected to power system or connecter separated system. It is possible to use this generator as energy source in small power pli In this paper we investigated three-phase self-excited asynchronous gener Asynchronous machine can work as self-excited generator only at this time, when reai power is delivered to machine. Special selected capacitors were connected to the mac for realization this task. The research carried out revealed that the slope of the exs characteristics decreases by reducing the number of revolutions of the asynchra generator and by adequately increasing the capacity of capacitors connected to the s circuit. The maximum load current {I\ = 2,68 A) of the asynchronous generator measured under the following conditions: the revolutions n = 2000 min"' =const am capacitors capacity C = 120 uF =const. The results showed that it was 43 % less tha nominal current of the asynchronous motor (/„ = 4,7 A). It can be concluded that excited asynchronous generator was not exploited to its full capacity
