7、troductionThe need for a guide to assist the electric utility industry in the analysis of failures related to systemcomponents has existed for many years. Extensive efforts have been made to develop such guides, but theseefforts have frequently stalled because of the complexities involved. Many of t
8、hese efforts have focused onthe development of a classification system intended to categorize failures for the purpose of statisticalanalysis and industry wide data reporting of failure rates. However, the real value of failure analysis is inimproving system performance, reliability, and increasing
9、personnel safety.This guide introduces a new approach that attempts to employ flow-charting techniques to lead aninvestigator through the steps necessary to identify the cause of a failure. However, the guide is not intendedto be either all-inclusive or to be a document that can take the novice inve
10、stigator through a failure analysisto the point of arriving at a reasonable conclusion regarding the exact cause of failure. Experience is ateacher that opens the mind to other possibilities beyond those that may seem obvious on the surface. Assuch, this guide is intended to provide documentation of
11、 failure mechanisms that have been identified inprior investigations and of the steps that may have led to the conclusions drawn. As investigators contributenew experiences and new instances of analysis, the guide will evolve to address new issues and theevolution of products developed to address th
12、e ever-changing needs of the electric utility industry. It willalso serve as historic documentation of past shortcomings in engineering, design, application, andmaintenance. In this way it is hoped the guide will contribute to continued product improvement and to theprevention of repeating the same
13、mistakes in future product designs and applications.This guide is the first of what is proposed to be a series of guides related to a common subject. The serieswill be designated by a common overall number with a point system of additional guides intended to addressspecific topics in failure analysi
14、s of the cable and accessories used on an underground electric utility system.Subsequent guides will specifically address cables, joints, terminations and separable insulated connectorsrespectively. The present guide attempts to establish a common format, methodology, and procedures forthe developme
15、nt of the subsequent guides. It is also intended to provide the background informationnecessary to introduce an individual to the concepts and principles of failure analysis.Much credit is to be extended to the Edison Electric Institute for its early efforts to develop a failure analysisguide for la
16、minated insulated power cables. That guide ultimately resulted in a cable system design that washighly reliable and had an enviable history of service. Hopefully, this series of guides will extend thatexperience into the realm of modern cable systems.Notice to usersErrataErrata, if any, for this and

33、rough 46 kV 1. Overview This guide serves as an “umbrella” document for a series of guides intended to cover specific methods of failure classification and analysis for cables, joints, terminations, and separable insulated connectors used on underground electric power systems. To improve or maintain
34、 electric system reliability, many companies depend on accurate failure analysis to optimize maintenance budgets and develop improved material specifications. This series of guides will not make the user an expert in failure analysis. It will, however, provide a general background on specific method
35、s that can be used or specified when performing failure analysis. 1.1 Scope This guide provides an introduction to failure analysis. It is the first in a series of guides covering failure analysis for cables, joints, terminations, and separable insulated connectors used on shielded power cable syste
36、ms rated 5 kV through 46 kV. Each subsequent guide will address failure analysis of a specific component of the underground power cable system. The following guides are planned for the series. g16 Guide for Investigating and Analyzing Shielded Power Cable Failures on Systems Rated 5 kV through 46 kV

38、hrough 46 kV. 1.2 Purpose The purpose of this guide is to provide an introduction to the concepts of failure analysis, how it can be used, and the value that can be obtained. The guide covers some of the commonly used methods employed in failure analysis and how these methods can be applied in deter
39、mining the cause of failure for the components used in the construction of an underground power cable system. The guide is based on the application of flow charting methods to the analysis of a failure. Ultimately, the guide will serve as a source for documenting known failure mechanisms and will pr

Many companies develop and use failed material return forms to initiate the information gathering process and track failures using a computerized database to recognize and evaluate trends. 4.1 Determination of what failed In some cases, it may be difficult to establish exactly what failed. Damage may be present in several locations. An initial failure may have created a cascade of events that led to subsequent failures of other components. In such situations, the most severely damaged area may not be the one where the failure
