[HCRA] electromagnetic fields/rfi

Hello, my name is Matthew Allen, and I'm an
undergraduate at UMass Amherst.  I'm
studying mechanical engineering, and I was wondering
if perhaps any of you 
could lend me some advice/expertise in regards to a
research project I'm 
working on this summer.  I am trying to get an idea of
what the 
magnetic/rf/electrical field is around commercial wind
turbines, but I've been 
having trouble finding information on the subject. 
The turbine I'm looking at 
specifically produces 3MW at the generator, so I am
assuming the EM field 
extends pretty far.  How would you recommend measuring
the RF power density?  I 
was thinking perhaps I could just measure the RF power
density at 60 Hz- what 
type of test equipment would I need to do this?  I
thought this research might 
interest the ARRL and the amateur community,
considering the EMI produced by 
wind turbines of this scale.  

Anyway, thanks for any help/insight you can provide.  


Matthew Allen, KB1LFF
