Specialty Transformers for Oil & Gas

NECO S-A-T (Select-A-Tap)

The NECO Select-A-Tap is a single-phase pole mounted transformer designed to give full rated kVA and amperage while containing constant impedance over the range of voltage settings. The primary voltage can be designed to meet your needs with dual voltages possible on request.

  • 2 external 9 position secondary tap changers and 4 bushings
  • Range of secondary voltages is from 480 to 960 Delta and from 960 to 1920 WYE
  • Extended Delta operations allow a variety of higher secondary voltages

3ph VFD Rated Transformers

NECO three-phase VFD transformer for the variable frequency drive application. These transformers have been very successful and approved by the leaders in the submersible pump industry.

  • Maximum input voltage of 480 volts – 60 Hertz
  • Output voltage range of :
    • 720/2703Y
    • 1060/3811Y
    • 1560/5335Y
  • Available in sizes from 83 kVA through 1500 kVa
  • Output ranges can be adjusted to meet customer requirements

3PH-6PH Phase Shifting Transformers

Our phase shifting autotransformers three-phase utility voltage to a balanced six-phase, 30-degree supply to provide the input for 12-pulse variable frequency drives (VFD).

  • Harmonic distortion in mid 3% range at full load and 12-pulse level
  • IEEE harmonic requirements met at PCC and load site
  • Models ranging from 120KVA to 1000 KVA
