8DA/B10MTBF (1)
The term major failures and minor failures are taken from the CIGRE publication of the work group 13.06 “Reliability of High Voltage Switchgears”.
Definition:
MTBFMeantime between failure
Major failure (MF)Complete failure of a panel which causes the lack of one or more of its fundamentalfunctions.NOTE: A major failure will result in an immediate change in the system operating e.g. the backup protective equipment being required to remove the fault, or will result in mandatory removal from service for non scheduled maintenance (Intervention required within 30 minutes).
Minor failure (mF)Failure of a panel other than a major failure or any failure, even complete, of a constructional element or a sub-assembly which does not cause a major failure of the panel.
MTTFMeantime to failure
