| Abstract: | By using the obliquity monitor device and the pull sensor at the hanging point of the conductor and combining calculations on the maximum sag and length of the conductor within the span,a standard model for calculating the weight of ice accretion on conductors was deduced which can be used to accurately judge the ice accretion situation for overhead lines under limited monitoring conditions.What's more,the practical model does not need large amount of experiential data and complicated weather factors. |

| Keywords: | transmission line obliquity stress the maximum sag thickness of ice accretion weight of ice accretion |
