Bharadwaj, Raj Mohan and Prabhakar, BR (1996) Effect of Humidity on the Breakdown of Air Gaps under Oscillatory Switching Impulse Voltages. In: Conference Record of the 1996 IEEE International Symposium on Electrical Insulation, 16-19 June, Montreal,Quebec,Canada, Vol.1, 320 -323.
Experimental investigations were carried out to study the effect of humidity on the breakdown of rod-plane gaps subjected to both unidirectional and bi-directional oscillatory switching impulse voltages. The humidity ranged from $14.1 - 36 gm/m^3$ at a constant temperature of 40' C. The gap subjected to uni-directional 6.3, 10, lQ kHz and bi-directional 4.2, 10,20 kHz oscillatory switching impulse voltages. The gap distance was varied from 8 to 30 cm. The experiments were carried out in a controlled atmospheric room. The results indicate an increase in breakdown strength with increase in humidity. The results are of great relevance at atmospheric conditions existing in Tropical countries.
