Kalman Filter Based Prediction of Remaining Useful Life of Aerial Bundled Cables

Aerial Bundled Cables (ABC) are increasingly overtaking the traditional based overhead low voltage power transmission system. These cables are not only safer as compared to the bare wires but are also very useful in reducing the electricity pilferage. However, the maintenance agencies need to know the viability of the ABC in all-weather conditions and require proper solutions for degradation assessment of such electrical infrastructure. This paper studies the thermography data of live ABC in varying temperature conditions to analyze a changing trend of healthy cable to unhealthy one. Further this paper discusses the application of Kalman filter on acquired trend to predict remaining useful life of ABC. The suggested method will help to maintain and plan replacement of cables prior power failure.
