Generator step-up transformers serve as the essential connection between power stations and transmission networks, operating continuously under full load.
Designed to endure extreme thermal demands, they prevent premature aging while maintaining reliability.
These transformers elevate generator-level voltage to transmission-ready levels and are available as single-phase or three-phase units, ensuring versatility and performance for various applications.
Shell-formed transformers
Core-formed transformers
Substation autotransformers efficiently reduce high-voltage levels to lower voltages, such as stepping down 400 kV to 220 kV.
Autotransformers generally feature on-load tap-changers (OLTC) for precise voltage regulation responsive to changing load demands.
Our transformers feature advanced monitoring and control systems, ready for smart grid integration.
We use high-grade European parts for durable, reliable, and high-quality transformers.
We use biodegradable, non-toxic oil for insulation and cooling, ensuring eco-friendliness and supporting sustainability.
Shunt reactors improve energy efficiency by absorbing reactive power, making them essential for stabilizing long high-voltage transmission lines and cable systems.
Mobile transformers provide rapid, flexible power solutions for temporary needs. Ideal for planned maintenance, capacity increases, or unforeseen outages, they ensure uninterrupted power delivery.
Compact and versatile, these units simplify deployment in tight spaces and can quickly switch between tasks, offering reliable support during repairs or natural disasters. They serve as backup power sources and maintain energy flow during substation maintenance without impacting consumers.
Northfield Transformers meet internationally recognized standards and can also be customized to address specific regional requirements. Our products meet IEC and ANSI/IEEE guidelines for safety, reliability, and performance.
Additionally, our manufacturing partners have region-specific certifications to ensure compliance in diverse markets:
Australia & New Zealand (AS/NZS)
Indonesia (SPLN)
Great Britain (BS)
