Re: www.vlf.it update
I don't talk about the geometry of the lines up in the air.
Your photo shows a 3 phase supply system.
We need to look at the voltages only: in a 220 kV system we have
pahse A : u(t) = sqrt(2)*220000 * sin ( 2* pi*50 *t )
pahse B : u(t) = sqrt(2)*220000 * sin ( 2* pi*50 *t + 120 degrees)
pahse C : u(t) = sqrt(2)*220000 * sin ( 2* pi*50 *t + 240 degrees)
These phase offsets do have a prominent influence on the far field E vector.(a distance large in comparison to the distance between the lines - this is where geometry really counts)
Likewise for the current under your assumption of purely resistive load.
I think you do it right only the text was misleading to me.
- A new monitoring station has been added to the Openlab VLF Observatories Network.
Laurentian University Radio Observatory
With Live data from Sudbury, Ontario, Canada:
It is maintained by Kevin Saroka. Thanks Kevin!
Meanwhile continues with great success the measurement campaign on very low frequency signals "Opera2015"
It is oriented to the study of geomagnetic pulsations, and the possible presence of seismic radio precursors. Comments and suggestions are always welcome!
