The results of an experimental study of the operation 
of a three-phase single-chamber arc plasma generator with sliding 
arcs are presented. The efficiency and mass-average temperature values 
and their dependences on external parameters have been obtained. The 
structure of the flow in the output cross-section of the plasma generator 
is considered.
