They will likely not know what you are talking about, they may create a ticket, but refer to the EMF department, or not create a ticket because they do not understand, please hold while I talk to my manager...

I showed them the noise and they recorded it.  They left the house, returned 2 hours later with a location.  Unfortunately for me, it wasn't a power line, rather, noise from someone's house 600 feet away.  I felt a little embarrassed that I didn't do due diligence and perform a DF hunt before they were called.  But, they said this is our job...  Next time, I'll do better.
