Abstract

The estimation for state of cable is significant to state of cable management. The famous methods for state estimation of cable are Weibull distribution model and Arrhenius method. The two methods are analyzed and researched. A method for measurement of Arrhenius model activation energy is presented. And the Weibull distribution model is used for state estimation of cable. The simulation based on overhaul data, test data and monitor data of the cables for Arrhenius model shows the effectiveness of the approach.
