Online Monitoring System

Based on the characteristics of power cables, an intelligent online monitoring system is constructed for failure detection and positioning. The implementation idea is illustrated and the main functions of the system are introduced in this paper. When power cable is destroyed or stolen, the system will send warning messages to alert the power management department. The actual applications show that the system has the advantages of convenience, low cost and high reliability.

Types Of Faults

Thefaults in the underground cables cause to generatetransients which propagate along the power cable as travelling waves. The velocity of the generated travelling wave and the time taken by a wave to reach the source point from the fault location enables us to calculate the fault distance value.In this paper a double endedtravelling wave based approach is used and a communication channel is designed to calculate the fault distance. A circuit-based model is developed in the EMTP-RV software to find out the fault distance from the source end for all types of faults. Further it is proved that the fault distance is unaffected by the change in ground resistance, various types of faults and the fault inception angle in the proposed method
