Abstract :
The influence of acid rain on the tracking deterioration of organic insulating materials by the artificial acid rain, has been investigated. The ingredient of the solution was determined by the density of ion in precipitation. The various non-filled pure organic samples, are soaked in the solution. Then contact angle of these samples are measured, and the sample is evaluated by Inclined Plane method of IEC 587. Test results show that due to the aging of acid rain surface of the material becomes more rough, and the surface hydrophobicity decreases, which results in the decrease of the tracking resistance of the materials
