    1. IEEE Switchgear Committee Meeting Pittsburgh, PA

    2. Reliability Centered Maintenance Example: Commercial Aircraft Industry DC 8 required 339 overhaul items, DC 10 required 7. Greater than 50% reduction in spare parts inventory Cost reductions achieved with no reduction in reliability

    3. Reliability Centered Maintenance

    4. Circuit Breaker Failures

    5. Objectives of Monitoring Utilize Design Know-How To: Identify impending failures (direct & indirect impacts) Reduce routine maintenance Reduce Total Cost of Ownership

    6. Condition Monitoring Unit

    7. Travel Sensors

    8. Current Sensors

    9. Diagnostics Approach On-line vs. off-line monitoring Data analysis vs. data collection e.g. interrupter wear calculation

    10. Diagnostics Approach (cont.) e.g. Operating mechanism charging system

    11. CMU Installation (<242 kV)

    12. CMU Installation (362-550 kV)

    13. CMUControl Software Graphical display of CMU data Modem dial-up capabilities (MODBUS for network connections) Automatic setpoint creation for commissioning tests Loading and updating CMU software
