Abstract
This experimental study showed the tracking characteristics of contaminated insulating materials. To analysis tracking characteristics, IEC 60112 was used. As the results of this study, the tracking characteristics of contaminated insulating materials showed as followings: (a) Comparative tracking index (CTI) of contaminated insulating material was lower than non-contaminated one. (b) First carbonized growth time and track growth time of contaminated insulating materials was faster than non-contaminated.
