In this paper, it studied parameters of low-temperature plasma (LTP) used in systems for cleaning waste gas. LTP created by positive nanosecond corona discharges, generated by high voltage pulses with a rise time of 50 ns, duration up to 400 ns, an amplitude up to 90 kV and pulses repetition 50 - 1000 Hz in coaxial electrode system with gap space 3 - 10 cm through which moving air with linear velocity v = 0.01 to 10 m/s. It was found that parameters of LTP depended on the flow velocity. The results of probe measurements of streamers current showed that on the above gaps and pulse parameters took place streamer breakdown with average field strength less than 10 kV/cm. This limits the energy input into the gas via a streamer corona and, accordingly, productivity of cleaning plants.
