Power Transformers
Northfield power transformers directly impact grid reliability and profitability, and our rigorous full-acceptance testing ensures every unit gives you unmatched quality and performance.
We’ve delivered transformers and components to support critical infrastructure across the world, with options including:
-
Generator Step-Up Transformers
Generator step-up transformers are the essential connection between power stations and transmission networks, operating continuously under full load. They elevate generator-level voltage to transmission-ready levels.
Our transformers are designed to endure extreme thermal demands and are available as single-phase or three-phase units, maximizing your performance and versatility.
-
Autotransformers
Ideal for voltage regulation and interconnection between grids, substation autotransformers efficiently reduce high-voltage levels to lower voltages.
Our autotransformers typically feature on-load tap changers (OLTC) for your precise voltage regulation responsive to changing load demands.
-
Shunt Reactors
Shunt reactors improve energy efficiency by absorbing reactive power. They’re essential for stabilizing long high-voltage transmission lines and cable systems.
-
Mobile Transformers
Mobile transformers are essential in emergencies and maintenance, providing rapid, flexible, and adaptable power solutions. When you have planned repairs, capacity increases, or unforeseen outages, you can ensure your power delivery remains uninterrupted.
Our mobile transformer units are versatile and compact, offering you reliable support that can quickly switch between tasks. The best part: Your customers won’t experience any changes in their service.
