The cost of global replacement of aging underground facilities is prohibitive. Consequently, utilities require an enterprise approach to managing underground power cable systems (cables, joints, and terminations) in order to develop prudent investment and maintenance practices. Utility power cable fl eets consist of many millions of feet of cable installed under city streets, suburban developments and, in some cases, in the countryside. Utilities have a long underground system history, with some of these systems installed as early as the 1920s. Increasing failure rates on these older systems are now adversely affecting system reliability, and it is readily apparent that something must be done to manage the consequences of this trend. Industry-leading utilities have ap proached this challenge by considering cable assets from a full-life-cycle

Managing a population of aging equipment requires considering three distinct phenomena: 1) representing the dynamic processes of failure and replacement of the equipment; 2) projecting changing failure rates as equipment ages; 3) balancing the costs of equipment failure with replacement
This paper presents a general decision model that enables utilities to generate business cases for asset management policies, with a specific application to underground distribution cables. The model takes a life-cycle costing approach that enables corporate financial managers and regulators to assess the multiyear financial impacts of maintaining specific classes of power delivery infrastructu...
متن کاملPrediction of Incipient Faults in Underground Power Cables Utilizing S-Transform and Support Vector Regression
Incipient faults usually emerge from partial discharges which eventually cause insulation degradation between two insulated cable cores. Early detection of incipient faults is of particular importance because insulation defects caused by incipient faults may lead to permanent faults in underground distribution networks. This paper presents a novel approach using S-transform and support vector r...
متن کاملAdaptive Neuro-Fuzzy Inference System for Thermal Field Evaluation of Underground Cable System
The influence of thermal circuit parameters on a buried underground cable is investigated using an ANFIS (adaptive neuro-fuzzy inference system). Finite element solution of the heat conduction equation is used, combined with artificial intelligence methods. The cable temperature depends on several parameters, such as the ambient temperature, the currents flowing through the conductor and the re...
متن کاملElectromagnetic Field Application to Underground Power Cable Detection
Before commencing excavation or other work where power or other cables may be buried, it is important to determine the location of cables to ensure that they are not damaged. This paper describes a method of power-cable detection and location that uses measurements of the magnetic field produced by the currents in the cable, and presents the results of tests performed to evaluate the method. Th...
متن کاملCalculating Intermediate Faults in Underground Cables
Short-circuit calculations are extremely important in the application and setting of protective relays and the analysis of power system operations. This paper illustrates the calculation of fault currents and voltages during intermediate faults in underground cables, taking into consideration the cable sheath bonding and grounding method. The compensated ground loop impedance for faults along t...
