PowerVar LV

The PowerVar low voltage capacitor bank offers a complete range of high quality power factor correction solutions engineered to compensate reactive power and harmonic distortion. These are easy and flexible solutions that can immediately boost your facility’s energy efficiency and productivity by maintaining the power factor at an optimum level.

  • Programmable to automatically add/subtract capacitor banks to maintain pre-set target power factor
  • Heavy-duty, three-phase capacitor construction
  • 5 year warranty of cells
  • UL and CSA listed
  • Optional molded case circuit breaker, rated 65 kAIC at 480 V and 600 V
  • Personnel ground fault interruption provides protection in case of accidental contact with control power and ground
  • Bottom cable entry spacing
  • 20 kvar (50 kvar for filtered) to 1200 kvar @ (208-600V)
  • BFI, CLI, main breaker, and fuse disconnector as an option
  • Detune or single tune design; multi-tuning as an option
Capacitor Cells:
  • Self-healing, low loss metallized polypropylene dielectric film
  • Solder-free connections
  • In addition to a PCB-free, flame-resistant mineral filler material, the casings also contain an adhesive stabilizer
  • Three-phase overpressure disconnector
  • Discharge resistors to reduce residual voltage to less than 50V in one minute
  • Operating temperature of -40°C (-40°F) to 60°C (140°F)
  • Three phase copper wound gapped iron core reactor
  • Nominal current rating of 135% of rated capacitor current for detuned application and of 150% minimum for filter application
  • Designed for maximum of 110°C rise at rated current
  • Center phase temperature sensor for overload indication or step tripping
  • Tuning to 4.1st, 4.7th or any specific frequency required
  • Class H (220°C) insulation. UL and CSA listed
Enclosure: Nema 12 standard, 12-gauge steel with ANSI 61 light gray dry powder baked enamel. Options:
  • Nema 3R
  • Shipping splits
  • Special paint
  • Bus duct entry
  • Back to back construction
Ventilation: Forced ventilation sized per kvar rating with filtered intake vents. Layout: Modular construction with bottom installation of capacitors to ensure low ambient (less than 46°C) for these temperature sensitive components. No stacking of components to avoid heat build-up conditions. Fusing: Standard Class J fast acting, 200KA type fuses mounted on three phase fuse blocks with rated current of 150% of capacitor nominal current to insure both short circuit and overload protection. Pilot Light Indication: Each step is equipped with three neon light indicators for steps on and blown fuse indication. Incoming: Power blocks are standard on smaller bank (<500 kvar) while copper bus is provided on larger unit. Standard location is for top incoming.
  • Internal digital display of power factor, load current, voltage, and number of energized banks.
  • Programmable time-delay controls capacitor switching.
  • Output relays disabled within 15 milliseconds of main power interruption.
  • Non-sequential switching.
  • LED displays.
Control Auxiliaries:
  • Internal CPT provided with breakers primary and secondary protection
  • CT shorting block provided for easy change of polarity
Optional Alarms:
  • Target power factor not reached
  • Loss of control power
  • Reactor overtemperature
  • Cabinet overtemperature / fan failure
Other Options:
  • Main breaker
  • Main fuse switch
  • Special incoming: bottom, bus duct, etc.
  • Special enclosure
  • Special voltage rating
