This guide provides direction for the selection of monitoring and for diagnostic parameters to be used with high-voltage circuit breakers (i.e., above 1000 V ac). 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 expectations. The analysis includes a failure modes and effects analysis (FMEA) of the circuit breaker and associated components, an analysis of the risks associated with failure of the specific application, and a discussion of the 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 of application. FMEA, as well as failure modes, effects, and criticality analysis (FMECA), are methods of reliability analysis intended to identify failures that have significant consequences affecting the system performance in the considered application. NOTE--The examples shown are for illustrative purposes only. Numeric and financial values shown are solely for the purpose of showing that values can be assigned if so chosen. Actual circumstances will dictate values, costs, and expenses 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 condition of a circuit breaker. Use of techniques, such as those in CEA Project No. 485T1049 (1997), provides more information on combining appropriate signals to derive greater information than either signal alone would provide. Circuits associated with the operation of the circuit breaker, which might include auxiliary contacts, X and Y relays, lockout switches, and so on, are included in this guide. External control circuits are not included in the scope of this guide. This guide is not intended to provide guidance on the monitoring of protection and control circuits, although they can have a significant effect on the overall circuit breaker functions.

This guide describes methods to protect a power system from faults that are not cleared because of failure of a power circuit breaker to operate or interrupt when called upon by a protective relay. The intent is to give the reader a guide in how to detect that a breaker has failed to clear a fault, and how to electrically isolate the fault after the breaker has failed to clear the fault. Additionally, schemes that provide primary protection of the power system from performance failures of the… read more power circuit breaker other than fault clearing failures such as failure to operate, either tripping or closing, manual or automatic, are also described. Such schemes, when applied, are typically integrated as a part of the overall BFP scheme. Also covered are recent practices that take advantage of new technologies. read less

This standard applies to enclosed low-voltage ac power circuit breakers as described in American National Standard for Low-Voltage AC Power Circuit Breakers Used in Enclosures, C37.13-1973 (IEEE Std 20-1973), except that the circuit breakers discussed in this standard incorporate current-limiting fuses as an integral part of the circuit breaker. The entire device thereby becomes capable of interrupting short circuit currents up to 200 000 A rms and may be applied on circuits where the available… read more short-circuit current does not exceed that amount. read less
