How It Works

How a Wind Generation Transformer Works

A wind generation transformer connects the wind turbine generator to the collector grid — stepping up the generator output voltage to the grid injection level for efficient long-distance transmission with minimal losses.

01
Wind Turbine Generator Output

Wind turbines generate electricity at low voltage (typically 690V or 1000V) - the transformer primary winding receives this through the nacelle or tower-base connection point.

02
Electromagnetic Induction Through CRGO Core

The alternating current creates magnetic flux in the CRGO silicon steel core - grain-oriented steel minimises core losses even under the variable generation cycles unique to wind energy.

03
Voltage Stepped Up at Secondary Winding

The secondary winding induces a higher voltage (typically 11kV or 33kV) at the output terminals — stepping up for efficient transmission through the collector cable network to the substation.

04
Oil Cools and Insulates Throughout

Mineral or ester oil circulates around the core and windings - critical for wind transformers which face frequent load cycling and must handle rapid thermal changes during variable wind conditions.

Trinity Cleantech manufactures wind generation transformers from 500 kVA up to 5 MVA for onshore and offshore wind energy projects. Custom configurations are available for all turbine ratings, collector voltages, and grid connection requirements. Both OCTC and OLTC tapping options are available.

Wind generation transformers are specifically designed to handle the variable load profile of wind turbines - including frequent load cycling, harmonic content from power electronics, and rapid thermal changes. They require robust insulation systems, low losses under partial loads, specific vector groups for turbine-grid compatibility, and often higher short-circuit impedance for fault protection in wind farm collector networks.

Yes. Trinity Cleantech wind generation transformers are BIS approved and comply with IS:2026 and IEC:60076 standards. The company holds ISO 9001:2015, ISO 14001:2015, and ISO 45001 certifications. All units are 100% factory-tested at the Jadcherla, Telangana facility before dispatch.

Trinity Cleantech wind generation transformers are available in all vector groups including Dyn11, Dyn5, Yzn11, YNd, and others as required by the turbine manufacturer and grid operator specifications. Custom vector group configurations are accommodated as part of the project engineering process.

Yes. Trinity Cleantech supplies wind generation transformers for onshore projects as standard. For offshore and coastal applications, enhanced sealing, corrosion-resistant fittings, and biodegradable ester oil options are available to meet the demands of marine environments. Contact our engineering team to discuss project-specific requirements.

All wind generation transformers are designed, wound, assembled, and tested at Trinity Cleantech's 20+ acre manufacturing facility at Plot No. L19-L28, TSSIC Green Industrial Park, Jadcherla, Mahbubnagar District, Telangana - approximately 80 km from Hyderabad. The facility features automated production and in-house testing laboratories.
