A Method of Calculating Fault Rate of Power Cables Based on the Influence of Temperature Changes
Thermal transients can cause a sudden increase in internal temperature of power cables,leading to faults.In view of this,the present work studied a method for calculating failure rate of power cables based on the influence of tem-perature changes.By fully considering the impact of thermal transients on calculation of cable failure rate,a neural net-work model was established to calculate the failure rate of power cables.The proposed method was verified by simulation analysis capable of obtaining results closer to true value compared with rated value of failure rate,and hence more accurate in calculating failure rate of power cables and helpful to ensuring stable and high-quality power supply.
