Frequently Asked Questions
What is the role of the step-up transformer in a wind farm?
It raises the turbine or collector system voltage to the grid interconnection level, allowing power to be transmitted with acceptable losses.
How is the transformer adapted to fluctuating wind output?
Loading profile, thermal design and cooling are engineered for the cyclic loading typical of wind generation, and tap range can be set for collector voltage variation.
Is a special design required for offshore or coastal sites?
For coastal and offshore applications, enhanced corrosion protection and enclosure ratings are specified according to the site environment.
What voltage ratios are typically supplied?
Common collector-to-grid ratios follow the project design; the exact ratio and impedance are engineered to your grid study.
Are routine tests performed on every unit?
Yes. Every unit undergoes routine testing before shipment, with test reports issued for the project file.
