heal.abstract	This Letter deals with the ionisation phenomena in non-uniform medium air gaps stressed by lightning impulse voltages. The application of the Townsend theory for homogeneous fields, still yields quite reasonable results for the tested inhomogeneous experimental electric field setup. Measurements taken on rod-plane air gaps, with clearance of 20 to 50 cm, show that the inception of the ionisation phenomena is related with an increase of the voltage across the gap that is characterised by a potential step of the voltage waveform. This phenomenon is related with the emission of infrared radiation. (C) 2000 Published by Elsevier Science B.V.	en
