POWER SYSTEMS ENGINEERED BY DOV UNITED

EMERGENCY STANDBY POWER

    • Medium voltage and low voltage generators up to 4000kW

    • Paralleling multiple gensets with onboard or standalone controls

    • Soundproof enclosures with custom-designed access platforms

    • Extended fuel storage tanks designed for fire marshal compliance and equipped with precision fuel monitoring

    • Load shedding and load bank testing

    • Tier 2, 3 and 4 emission compliance

    • Automatic switches with Open or Closed power transfer

    • Manual switches or docking stations with quick-connect receptacles for portable generator hookup

    • PLC based transfer controls within switchgear and switchboards

MOTOR CONTROL AND PROTECTION

  • Variable frequency drives where precision speed control, minimal inrush current and advanced motor protection are required.

  • Harmonic mitigation and filters: Ensure system harmonics meet IEEE 519 and don’t cause damage to the rest of the electrical system.

    • Reduced voltage soft starters where constant speed is acceptable, but inrush current needs managed to meet utility standards or extend motor life.

  • Across-the-line (full voltage) motor starters where high inrush and constant speed is suitable.

  • Electromechanical relay control schematics or PLC based control narratives

  • Motor protection relays: detect power faults on the motor circuit.

  • RTD monitoring: detect excessive thermal conditions within motors and pump bearings.

  • Vibration monitoring: detect mechanical abnormalities around the motor and identify issues before they cause a major failure.

RACEWAY, BOXES AND BUS DUCTS

  • Route your conductors in cable tray or trench to allow easy access to cables and the flexibility to add or remove conductors in the future.

  • The staple of conductor raceways. Options between PVC, galvanized steel, aluminum, PVC-coated steel/aluminum, and fiberglass. A good engineer selects conduit with the best combination of cost, strength, UV resistance and corrosion/chemical resistance for the application.

  • For underground applications. Duct banks consist of multiple conduits buried and encased in either concrete, sand or select fill.
