Abstract

The present invention discloses a health index system for predicting health condition in underground cables, comprising of: a processor and a memory communicatively coupled to the processor via a communications bus; a computational model communicatively coupled to the processor, wherein the computational model: receives a plurality of operating parameters for an underground cable; accumulates tangent delta (TD) signal data measured (102) based on the plurality of operating parameters for the underground cable; defines a composite health index (cHI) (104) based upon the accumulated TD signal data, a stability of the TD signal over time and a stability of the TD signal over voltage; calculates remaining useful life (RUL) (106) of the underground cable; analyzes the relationship of the cHI and RUL (108); and predicts the RUL model (110) using artificial intelligence (AI) based on the analyzed relationship between the cHI and RUL to determine the health condition of the underground cable.
