Three-phase induction motor can be operated as a three-phase induction generator.The tendency to use induction generators (rotor cage) as subtitute of a synchronous generator is also increasing, especially for small MHP with lighting load (resistive). Its because of the dificulty, hard to find in the market, and high cost,induction generator self-excitation has many advantages than synchronous generator. However, the induction generator offers low voltage regulation and its value depends on the driving speed, capacitors, and the load. In this study, a three-phase induction motor ( rotor cage) 0.9 KW, 2.7 A, pf 0.84, 50 Hz used as an induction generator, with capasitor connection variety, which capasitance value for star 25μF , Delta 8μF, C-2C 8μF and 16μF to load R-RL varied. And star connection capasitor with 25μF capasitance is better than others.
