| Abstract: | To solve the actual problem of power consumption peak of East China Electric Power Grid during 2003 summer, two methods of increasing allowable current carrying capacity of transmission line under current condition were introduced. The three problems possibly caused by the increased capacity were also analyzed. The increasing of allowable temperature of conductor from 70 to 80 has been proven feasible through analysis of related 500 kV transmission lines of East China Electric Power Grid. |

| Keywords: | transmission line allowable temperature distance to ground transmission capacity |
