A novel method for condition monitoring in cable in frequency domain Das Aritra, Reddy C. C. Department of Electrical Engineering, Indian Institute of Technology, Ropar Rupnagar, Punjab Online published on 27 September, 2023. Abstract One of the toilsome tasks in any power cable is to predict the location of the damaged part and short circuited fault. Scanty research is performed on condition monitoring in cable, and methods that are-available either have low accuracy or are extremely difficult to apply in the practical field, Among different methods, the most suited technique is reflectometry. Contrasting the reflectometry technique, a novel-method based on impedance spectroscopy in the frequency domain was used in this paper to identify the damaged part in a cable and also to locate the exact location of the short-circuited fault. The impedance spectroscopy was obtained using the sweep frequency response analysis (SFRA), where only the standing wave ratio is considered. The use of SFRA is an aged old practice for condition monitoring in the transformer. Using the same approach, condition monitoring and location of the short-circuited fault are achieved in this paper. A real-time problem to locate short-circuited fault is mentioned and along with the PSpice simulation for condition monitoring of cable has been discussed in this paper.
