Wind Turbine Transformers

They do seem to be the most popular....

Were you not supplied with the technical specifications by the wind turbine manufacturer or is this a homework question?

If you are going to install a wind turbine, contact the manufacturer and obtain the technical specifications.

Solar Eagle has provided a valuable info.If the dry cast transformer placed inside nacelle, Cooler fan's are installed.

Main reason to choose dry type is to avoid oil related problems.

Temperature rise of transformer to be monitored continuously (Make sure that it doesn't reach igniting temp of FRP Material) particularly during full generation period.

Above these are my personal experiences,Above things changes from one windmill manufacture to another.

The specifications should be selected to prevent this from happening...

Apparently they are hard to extinguish.

Thanks for above replys

Are the Slim type transformers more effective than Dry type transformer for nacelle installation?

Thanks and regards,

What do you mean by "more effective" Vinod?

Form follows function.

In addition to correct function, there is, size, weight, efficiency, safety, reliability, serviceability, operating environment paint colour and a host of other attributes that only the designer (you?) and the turbine's nacelle can consider. And then if it is only available in one form for the electrical characteristics required you have to determine how to negate any undesirable attributes that a compromise may stimulate.

What is your objective and what are your concerns?

By "more effective" i meant in fire risk between dry and slim type transformers.

my ojective is selecting dry type or slim type transformer for nacelle installations.

i am concerned with size, fire, vibration and noise level effects of the transformers for both types
