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.
