Abstract :
The influence of high humidity on the sparkover of a 40 cm square-ended rod-rod gap and round-ended rod-plane gap has been studied using impulse voltages of +1/1000 ¿S waveshape. Over the large humidity range 7¿27 g/m3 achieved, it was found that, for each increase of 1 g/m3 of water vapour, a corresponding increase in the mean sparkover voltage of 1% for the rod-rod gap and 1.25% for the rod-plane gap was obtained.
