Minimization of the Bypassing of High Voltage Insulators by the Attenuation of the Transient over VoltagesAbstract: In this research it is shown that the correct evaluation of the attenuation and the distortion of the over voltages of atmospheric origin while leaning at a time on the convenient experiences make on the line 220 kV and of the experiences of charges q = f(u). One deducts that the corona effects has impact only on the transverse constant and notably the capacity that undergoes a remarkable modification of the apparition of corona effects. The corona effects reduced the amplitude transient of the electrical constraints and the protective material inside the station because of the distortion of the amplitude of the wave also that the front of wave is sufficiently long for the enlightening functioning with the best efficiency without forgetting that this research contribute to the improvement of the electrical constraints and a best economic optimization and a perfection of bets in service of the protective device.
