I am looking for information concerning the location of a large transformer that is under a window near the first floor of a nine story building.

The problem is with the noise and constant humming and the distance from the building.
The transformer is located in-between two buildings.

Anything from EPA?

How close to the building?
What sized transformer?
Is it oil filled?
How old is it?
And many other questions.

The transformer is 750 kVA, and the oil is non PCB. I was told it was "regular transformer oil". The hum is very loud!
