Abstract :
Twisted pair samples of enameled wires are often considered as representative of real insulating systems and are used to validate a new process, changes in the quality of one of the enamel components... and influence of new voltage waveforms. In this paper two kinds of enameled wires are studied. One is supposed to be corona resistant and the other is not. Samples may be or not impregnated using the same varnish. Lifetime determination of these different types of samples is undertaken. Influence of voltage waveform (square 1 kV/μs rise-time or sinus), temperature and impregnation is discussed
