AUTO TRANSFORMERS

Auto Transformers  have the capability to supply a varying secondary voltage to supply a varying secondary voltage to an externally connected load. This is used predominantly is applications where various voltage outputs are required such as:

  • Electronics testing centers where continuously varying voltage supplies are required
  • Applications such as power stations which initially require a step up/step down followed by an increase/decrease to match the voltage required by the device at the receiving end
  • Motor starting applications

TESTING AND QUALITY ASSURANCE

As part of our quality assurance process, all K Factor Rated MGM Transformers go through a rigorous ANSI/IEEE test plan to ensure optimum performance. These tests include:

  • Winding resistance test
  • Turn ratio test
  • Polarity and phase relation test
  • No load losses and exciting current test
  • Impedance and load loss test
  • Applied potential test
ENCLOSURES
MGM ventilated transformers utilize a NEMA 2 rated drip proof metal enclosure with natural draft ventilation. MGM dual rated enclosures are suitable for indoor or outdoor applications and are standard on all models except the 225, 300, and 500 kVA transformers (optionalWeather-shield Kits are available for these units).
VOLTAGE TAPS

Taps will compensate for the high or low line voltages. K Factor Rated transformers are provided with 6 primary taps:

  • 2@ 2-1/2% FCAN
  • 4@ 2-1/2% FCBN
