• Impedance: 4–6%

• Losses: According to EU Ecodesign Tier 2

• Noise Level: ≤ 60 dB

• Insulation Class: IEC compliant

Low-loss transformer designs are increasingly mandatory due to EU environmental regulations.

4. Renewable Energy and Transformer Demand

Portugal is one of Europe’s fastest-growing renewable energy markets.

4.1 Wind Energy

Portugal’s wind capacity exceeds 6 GW and continues expanding.

Wind farms require:

• Step-up transformers (0.69kV → 20kV/60kV)

• Collector system transformers

• Auxiliary distribution transformers

4.2 Solar Energy

Solar capacity is rapidly increasing, especially utility-scale PV plants.

Typical solar transformer requirements:

• 800 kVA – 2500 kVA

• 0.8kV / 20kV

• Dyn11 configuration

• Outdoor oil-immersed design

• Anti-corrosion treatment

This creates strong demand for IEC-compliant renewable energy transformers.

5. Regulatory and Compliance Requirements

Entering the Portugal transformer market requires strict compliance.

5.1 Mandatory Standards

• IEC 60076

• EN 50588-1 (EU Ecodesign Regulation 548/2014)

• CE Marking

• RoHS Compliance

• ISO 9001 Quality Certification

Failure to meet EU Ecodesign efficiency levels disqualifies transformers from legal sale.
