Abstract :
Experimental equipment was developed to investigate commutation phenomena in gasoline and to test commutator materials. Experimental results show that the duration of commutation arc in gasoline is shortened by 30-50% than in air. Two reasons are determined by analyzing the results. One is that the residual current of commutation in gasoline is smaller than in air. The other is that arc voltage in gasoline becomes higher than in air
