Transformer Commissioning

Getting a transformer in place is only half the job — proper installation and commissioning are key to long-term performance and safety. At Protrafo, we specialise in turnkey transformer installations, ensuring that every unit is seamlessly integrated into your infrastructure. Whether it’s a brand-new installation or replacing an existing asset, we make sure your transformer is ready for reliable operation from day one.

Testing
General Measurements
Assembling

Our team handles everything from transport and site preparation to mechanical assembly and high-voltage connections. We coordinate closely with your on-site staff or contractors to minimise disruption and ensure that every step follows industry standards and safety regulations. All our technicians are certified and experienced in working with both oil-filled and dry-type transformers in demanding environments.

Tested, Certified and Ready for Operation

Before commissioning, every unit goes through a rigorous testing process. We check insulation resistance, winding ratios, grounding, protection settings, and more — all to guarantee flawless performance. Once all parameters are validated, we energise the transformer and perform final load tests to ensure safe and stable operation within your grid.

Protrafo goes beyond just installing equipment. We provide documentation, reporting, and optional training for your team, ensuring everyone involved is aligned and confident in operating the system. With our end-to-end approach, you’re not only getting a transformer installed — you’re investing in peace of mind.

Questions about Installation and Commissioning?

Yes, we provide on-site coordination and, if required, technical assistance to ensure a smooth installation process.

Transporting a transformer requires careful planning and handling to ensure safety and prevent damage. Depending on the size and type, transformers can be shipped fully assembled or in parts. Key steps include securing the unit on a reinforced pallet or skid, protecting components with transport covers, and using specialized lifting points. For larger units, Protrafo provides project-specific logistics, including route planning, crane coordination, and on-site delivery support across Europe.

Transformer oil serves two key purposes: insulation and cooling. It insulates internal components to prevent electrical faults and helps dissipate heat generated during operation. High-quality mineral or synthetic oils, such as MIDEL, also enhance fire safety and extend transformer lifespan.

Yes, our team provides on-site support for safe installation, electrical connection, and operational setup. We also offer temporary monitoring solutions such as Protrafo Insights® if needed.

Yes, Protrafo provides on-site diagnostics and repairs where possible, including thermal imaging, insulation tests, and minor component replacement. For complex repairs, the transformer may be transported to our partner facilities.
