IEEE C37.10.1-2000 pdf download IEEE Guide for the Selection of Monitoring for Circuit Breakers
1.Scope
This guide provides direction for the selection of monitoring and for diagnostic parameters to be used withhigh-voltage circuit breakers (i.e, above 1000 V). It provides guidance on appropriate parameters to be considered for monitoring applied to various circuit breaker technologies.
This guide will lead a user through an analysis of circuit breaker performance and application expectationsThe analysis includes a failure modes and effects analysis (FMEA) of the circuit breaker and associatedcomponents, an analysis of the risks associated with failure of the specific application, and a discussion ofthe items to be considered in a cost-benefit study to justify application of monitoring in its many forms.Monitoring is dependent on the technology of the circuit breaker and monitoring available at the time ofapplication. FMEA as well as failure modes, effects, and criticality analysis (FMECA) are methods of reli-ability analysis intended to identify failures that have significant consequences affecting the systemperformance in the considered application.
NOTE–The examples shown are for illustrative purposes only.Numeric and financial values shown are solely for thepurpose of showing that values can be assigned if so chosen. Actual circumstances will dictate values. costs. andexpenses to be used in the quantifying of risk, economic evaluation and justification, and the ultimate selection of monitoring. The specific circuit breaker technology employed will also either restrict or broaden opportunities for monitoring
This guide provides advice on what parameters can be monitored to derive information about the conditionof a circuit breaker Use of techniques. such as those in CEA Project No. 485T1049 (1997)-, provides moreinformation on combining appropriate signals to derive greater information than either signal alone wouldprovide.
Circuits associated with the operation of the circuit breaker, which might include auxiliary contacts. X and yrelays, lockout switches. and so on, are included in this guide. External control circuits are not included inthe scope of this guide. This guide is not intended to provide guidance on the monitoring of protection andcontrol circuits, although they can have a significant effect on the overall circuit breaker functions.
NOTE–This guide makes no attempt to address the many possible protection and control failure modes. These failuremodes are dependent on the technology of the protective devices as well as on the manner in which they are applied onthe power system.This issue of the guide does not address the subject of software used in protective. control, or monitor.ing devices and systems.
