OPTIMIZER2

OPTIMIZER2

The OPTIMIZER2 uses patented technology to continuously monitor in-service circuit breaker performance and SF6 gas density. SF6 gas emissions due to leakage are totalized and reported.

Applications

  • High voltage circuit breakers to 765 kV
  • Generator
  • Transmission
  • Distribution
  • Circuit Switchers
  • SF6 Puffer, Vacuum and Oil types, any mechanism type
  • Live tank and dead (grounded) tank

  • Capabilities

    The OPTIMIZER2 monitors and trends critical circuit breaker operating parameters:

    • 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
    • All performance metrics may be exported to MS Excel 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
    • The OPTIMIZER2 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.
    • The OPTIMIZER2 provides leading indicators of insipient breaker failure. Breaker failure relay schemes can only provide lagging indicators - once the breaker fails, it's too late.
