Howard Power Solutions' medium power substation transformers are designed and built to provide outstanding performance and reliability in the most demanding utility and industrial applications. Our current product scope includes ONAN/ONAF ratings up to 60/112 MVA with primary voltage ratings through 230 kV. An extensive range of features and accessories are available, including GSU units, Autotransformers, Dual voltage units, on-load tap changers, forced-air cooling systems, different types of fluid preservations systems, and other options to satisfy the special requirements of virtually any application. Our experienced design engineers employ the latest available computer-based design tools, including 3D CAD-parametric modeling, and finite element analysis, to ensure that our transformers perform as intended. Our new manufacturing facility was designed and built specifically for the efficient production of medium power transformers and is equipped with the latest available technologies including the vapor phase drying process, and test station capable to perform all tests per current IEEE standards.
Howard Industries manufactures a complete line of transformers, all designed with increased margins of safety and reliability. Contact your distributor or factory representative for availability of other kVA sizes, voltage ratings, features, accessories and design standards not listed.
