Forecasting Underground Electric Cable Faults Using the Crow-AMSAA Model
Guest Submission - Yancy Gill of the Salt River Project
One of the major economic and reliability challenges facing the Salt River Project (SRP), a major electric and water utility in the Phoenix, Arizona metropolitan area, is managing the replacement of 7000 miles of direct-buried primary electrical cable that is at or approaching the end of its useful life. Since cable replacement programs of this magnitude will require 25 years or more to complete, the ability to model cable faults as a function of cable replacement is critical to developing a sound cable replacement strategy. The model SRP selected to forecast faults in aging underground electrical cable is a reliability growth-based model known as Crow-AMSAA.

Reliability Basics
The Beta Factor Method
Common Cause Failures (CCFs) are single faults that result in the failure of multiple components. Typical examples include impact, vibration, temperature, contaminants, miscalibration, improper maintenance, etc. There are different methods to address CCFs, both qualitative and quantitative. In this article, we discuss the β factor method and provide an example of an application of this method using BlockSim 7.

Tool Tips
  • Can I customize the template for importing data into Xfmea 5 or RCM++ 5?
  • In Lambda Predict 3, can I define a system or a block to be in a parallel configuration?
