TESTING AND QUALITY ASSURANCE
As part of our quality assurance process, all 600 Volt MGM Transformers go through a rigorous UL/NEMA test plan to ensure optimum performance. These standard tests include:
- Winding resistance test
- Turns ratio test
- Polarity and phase relation test
- No load losses and exciting current test
- Impedance and load loss test
- Applied potential test
ENCLOSURES
Ventilated transformers utilize a NEMA 2 rated drip proof metal enclosure with natural draft ventilation. MGM Transformers dual rated enclosures are suitable for indoor or outdoor applications and are standard on all models except the 225, 300, and 500 kVA transformers (optional Weather-shield Kits are available for these units).
