Thc investigation of circuit breaker failures requires some preparation and training of personnel.
The importance of preserving evidence that will allow successful determination of’ the cause of the failure must be balanced with the needs for safety of restoration of service. An organization should recognize the sometimes competing goals of restoring electric service and determining the cause of the failure. It is important to declare the priorities, which may change during the course of the investigation.
Local or on-site personnel should be adequately trained to deal with immediate hazards, isolation, grounding etc. These personnel may not be in charge of the subsequent investigation of the failure. Therefore, an organization should decide well ahead of time who will be trained to perform the actions at the scene required to preserve evidence, as well as contacting the appropriate internal group who will organize or lead the foi-rnal investigation. There may be a separate protocol and level of detail for different levels of investigation, depending on the nature and initially perceived severity of the failure.
An overall corporate incident management plan with a plan to handle possible circuit breaker failure investigations is recommcnded.
Active and planned cooperation between the owner of the circuit breaker and the equipment manufacturer is highly encouraged and is almost certain to result in a more accurate assessment of the incident. Full sharing of information relative to the circuit breaker failure is essential to having a preductive process that will lead to improvements in circuit breaker design, manufacture, application, operation, and maintenance.
2. Normative references
The following referenced documents are indispensable for the application of this document (i.e.. they must be understood and used. so each referenced document is cited in text and its relationship to this document is explained). For dated references, only the edition cited applies. For this guide. undated references refer to the most appropriate edition of the referenced document and that edition applies (including any amendments or corrigenda). The investigation of circuit breaker failures requires use of references that are appropriate to the time when the circuit breaker was designed, tested, and applied to the power system. Annex H lists some historic versions and editions of circuit breaker standards.IEEE C37.10 pdf donwload.
