| Abstract: |
| Instructive analysis on power cable junction faults is carried out and an algorithm for indirect on line measuring of cable junction resistance and insulation aging is proposed. The interrelation of cable junction temperature and interconnection quality is theoretically proved, and a temperature monitoring system of power cable junction designed on that mechanism is introduced.By instance analysis the efficiency and believability of this mechanism are explained, and the reliability of this advanced monitoring system is verified. |
