Capabilities

  • Accurately times arc duration, trip, close, & clearing
  • Reports days since last operation
  • Monitors phase-segregated line current during interruption to gauge contact life
    • Detects restrikes
  • Gives precise time, in days, until breaker will lock-out on low gas alarm
  • Up to three SF6 density sensors may be used with a single OPTIMIZER2
  • Totalizes mass of SF6 lost to atmosphere for breaker lifetime
    • Useful in EPA reporting
  • May be installed temporarily, as-needed, on problem breakers for diagnosis
  • .xlsx file exported performance metrics for detailed review
  • Provides IEEE function 49, -40 °C definite temperature lockout

Features

  • Powered from AC or Station Battery
  • Accurate for 50 or 60 Hz Power Systems
  • Secure TCP/IP - HTTPS Digital Signing Encryption Layers
  • Auto-resets alarms after a gas fill operation, no user interaction required
  • Fast Installation - field retrofit in less than two hours
  • Fast Functions - Using the USB port and a memory stick, in seconds, the user may:
    • Clone any OPTIMIZER2 to Batch Program multiple OPTIMIZER2 units for a specific breaker type
    • Retrieve breaker performance history data
    • Reset parameters after a breaker service or rebuild
  • 16 user-defined PdM alarms
  • Remote communication using DNP 3.0 via Ethernet TCP/IP or RS485

Benefits

  • Every breaker operation is examined
    • Logs in-service performance metrics
  • Reduces need for off-line time/travel testing of circuit breakers
  • Displays SF6 Density & Contact life remaining in simple RED YELLOW GREEN format
  • No moving parts, reliable in temperature extremes, eliminates nuisance alarms
  • Provides IEEE function 63, low gas alarm lockout
  • Reports fault operations and switching operations separately
  • Forecasts SF6 refill deadline for use as a maintenance planning driver
  • Total unit cost can be recouped by avoiding emergency gas service calls
  • Integrates using SmartGrid DNP 3.0 Communication
  • No PC software to maintain, only a Web browser is needed
  • Provides "distributed intelligence" that remains attached to the breaker, not buried in a central processing location. It operates as a Web Server, making it independent of future MicroSoft OS changes.
  • Provides leading indicators of insipient breaker failure. Breaker failure relay schemes can only provide lagging indicators - once the breaker fails, it's too late.
