Abstract
We give a detailed analysis of intense pulsed corona dis
charges. CCD movies and current, voltage and energy in
put measurements are the basis of the description. The
discharges are generated in a 1.5 kW pilot unit, which cre
ates pulsed corona discharges energized by 100 kV pulses
of 200 us width, at a repetition rate up to 1000 Hz. The
corona discharges are characterized by 500 A and 50 MW
peak values of current and power respectively. The pilot
unit can be used for industrial applications: cleaning of
gases (100 m3/h) or fluids (e.g. waste water). In the pilot we
observe two main regimes, an initial streamer phase and a
resistive streamer phase. These regimes are also visible in
the CCD movies (5 us shutter time), which clearly show the
development of the pulsed corona discharge in space and
time. With the electrical measurements we were able to
calculate the energy input during each of the streamer pha
ses.
