IEEE 1325-1996 pdf download IEEE Recommended Practice for Reporting Field Failure Data for Power Circuit Breakers
1.Overview
Actual practices of power switchgear users in documenting field failures and failures of switchgear and other powerdelivery products vary widely, In order to restore failed elements to service, the emphasis often is to “clean up”aailure quickly, losing important data that is critical to corrective action. There is a real need for more depth in recordkeeping to improve reliability of power handling equipment, This recommended practice addresses this need
1.1 Scope
A Failure Reporting Form, figures 1 and 2. has been developed by the IEEE Switchgear Committee to improve thereliability of circuit breakers through uniform reporting of field failures. The use of this approach is the recommendedpractice for all users of power circuit breakers.
1.2 Purpose
The use of the Failure Reporting Form, included in this document, is recommended to standardize reporting of fieldfailures and to use these experiences to improve the reliability of power circuit breakers.
2.References
This recommended practice shall be used in conjunction with the following publications:IEEE Std C37.100-1992, EEE Standard Definitions for Power Switchgear (ANSI).
For definitions applying to this standard, refer to lEEE Std C37.100-1992
4.Recommended practice
4.1 Background
The form, figures 1 and 2, is derived from the experiences and with the approval of both manufacturers and users. Itsmain goals and requirements are to be simple to use, to define the field failure including its related environment. andto establish records and references for further analysis and action should the situation repeat itself or as other factorssurface.
4.2 General
Details of the one-page reporting form have been carefully developed by users and manufacturers to arrive at an easyto-use format that will contain enough information to understand the defined problem.
Although serious systems-related failures will require engineering input for figure 2, it is expected that the fieldmaintenance person will complete the front side of the form, figure l. The back side, figure 2, should be completed bythe user’s maintenance personnel with assistance, if required, from others.
The completed form, figures l and 2, should be sent to the person in the user’s organization who monitors fielcperformance of installed equipment. lt should be used to analyze the reported failures and communicate incident-specific information to the manufacturer, as appropriate, when there is a repetitive or serious problem.
4.3 Description of form
The front side, figure 1, is to be filled out for all failures and is an adequate report for minor malfunctions,nonconformances, or nonsystem related failures.
The back side, figure 2, is useful for further elaboration of major failures that are more complex, with considerationgiven to system interaction.
Both figures may be incorporated on a single sheet of paper and bound into pads for easy availability.
5.Implementation
Users should use this form, figures 1 and 2, as a record and feedback system to improve equipment reliability
Every effort should be made to promptly obtain and sort reports so that failures are prioritized to identify thosedeserving the most immediate attention. The success of this activity depends on a cooperative effort between the user’smaintenance and operations people and the original manufacturer, when their involvement is needed.
