Process High Current Duty Transformers

Process High Current Rectifier Duty Transformers are designed to handle non-linear, non-sinusoidal loads resulting from their use with a variety of power electronic applications such as chlor-alkali or copper electro winning applications with diode or thyristor configurations from 6, 12, 24, 36, 48, or 60 pulse configurations, single way with interphase transformers or double way.

Transformer Specifications

Special design considerations should be used to account for the additional harmonic heating, more severe axial forces, severe overloads and short circuit forces that can be seen as compared with a standard power transformer. Niagara Transformer’s superior engineering expertise paired with our unmatched years of manufacturing experience and high-grade materials allow us to provide the best in-class Process High Current Rectifier Duty Transformers.
