IEEE 1511-2004 pdf download IEEE Guide for Investigating and Analyzing Power Cable, Joint, and Termination Failures on Systems Rated 5 kV through 46 kV
1. Overview
This guide serves as an “umbrella document for a series of guides intended to cover specific methods offailure classification and analysis for cables, joints, terminations, and separable insulated connectors usedon underground electric power systems. To improve or maintain electric system reliability, manycompanies depend on accurate failure analysis to optimize maintenance budgets and develop improvedmaterial specifications. This series of guides will not make the user an expert in failure analysis. It will.however, provide a general background on specific ethods that can be used or specified when performingfailure analysis.
1.1 Scope
This guide provides an introduction to failure analysis. It is the first in a series of guides covering failureanalysis for cables. joints, terminations. and separable insulated connectors used on shielded power cablesystems rated 5 kV through 46 kV. Each subsequent guide will address failure analysis of a specificcomponent of the underground power cable system. The following guides are planned for the series.Guide for Investigating and Analyzing Shielded Power Cable Failures on Systems Rated 5 kVthrough 46 kV.
Guide for Investigating and Analyzing Joint Failures on Systems Rated 5 kV through 46 kVGuide for Investigating and Analyzing Termination Failures on Systems Rated 5 kV through 46 kV.Guide for Investigating and Analyzing Separable Insulated Connector Failures on Systems Rated5 kV through 46 kV.
1.2 Purpose
The purpose of this guide is to provide an introduction to the concepts of failure analysis, how it can beused, and the value that can be obtained. The guide covers some of the commonly used methods employedin failure analysis and how these methods can be applied in determining the cause of failure for thecomponents used in the construction of an underground power cable system. The guide is based on theapplication of flow charting methods to the analysis of a failure. Ultimately, the guide will serve as asource for documenting known failure mechanisms and will provide a format for the documentation of newfailure mechanism once they have been identified.
