1. I must say I am really not familiar with the situation in US, but I would
appreciate if Beau or Emil or someone from US inclined to technical issues
commented your statements about earth being used instead of neutral wire
(what you said means that, practically). I can't believe it happens that
way, but I am ready to hear the proven facts.

Shivani replies:
Yes, it means exactly what it sounds like. The utility wiring systems were
build about 50 years ago. They are incapable of returning today's high
frequency loads to the substations. Rather than making the utilities redo their
transmission wiring, the Public Service Commissions of the various states have
given them permission to use the earth, terra firma. The health-damaging
higher frequencies in particular are returning to the substations via the earth
(terra firma, dirt) as they are subject to the Skin Effect. These high
frequencies behave somewhat differently from 50 or 60 Hz. They flow to the
outside of wiring, and off of it. Then they flow onto the surface of whatever is
nearby, and not necsessarily things you'd usually think of as "conductive."
Where you have high frequency electrical pollution you will find RF electric
fields on things like hollow core wooden doors, wooden furniture, even rattan
furniture. Not to mention yourself!
You already did hear the proven facts. Both EPRI and the Minn. Science
Advisory Board have made this public.
There is presently only one place in the USA that does not allow the
utilities to use the ground (terra firma, dirt) to return the current, and that
is part of California. If a chemical company used your yard to shuttle its
toxic chemicals to its factory, you could get a lawyer to win a case for you
about that. So far, nobody has the power to win over the utilities regarding
this. Few people even know it is happening.

2. "GS units" mean - nothing! I have seen myself that "Stetzer meters" react
to vicinity of wires, but what they measure I still don't know. As you seem
to be in a contact with them at Stetzer's you might ask what the GS units
stand for. I am curious myself.
I have numerous meters, and can hire others, so just let's talk about the
figures! (Figures presuming usage of SI sistem of measurements what means
values like Tesla, Volt, Watt, meter, second, etc. :-))

Shivani replies:
You can go to www.stetzerelectric.com and read about the meters for
yourself. Including:

Microsurge Meter Design Criteria
Microsurge meters were specifically deigned as a companion to the STETZERiZER
filters. The meters measure the level of harmful electromagnetic "energy"
present, and their primary use is to guide effective filter installation.
Microsurge meters are low cost, robust, and easy to use by non-technical people. The
meters were designed to measure harmonics and other high frequency "energy"
present, which are the frequencies most detrimental to human health. The meters
effectively ignore the effects of 60 Hz power and other lower, less harmful
frequencies. Specifically, the meter measures the average magnitude of the
changing voltage as a function of time (dV/dt), which naturally emphasizes
transients and other high frequency phenomena that change rapidly with time. The
measurements of dV/dt read by the meter are defined as G-S (Graham-Stetzer) units
(since no standard term is available). The G-S units are a measure of "harmful
energy" which is a function of frequency, or more generally, rate of change of
voltage or dV/dt.

Shivani,
Regarding "1.", I am still waiting for others to comment the issue.
Meanwhile just to say it would have been usefull seeing the citations you
mention in their original context, as I firstly said...
By the way, I now remember that American home / office average is 1-2 mG =
impossiblity of significant descrepence between ingoing and outgoing
amperage!!

Regarding "2", I am certainly aware that GS meters are coupled with GS
filters, otherwise they would have been rediculed by their customers.
But "time derivative" means still nothing without being precisely related to
SI measures... Everything measurable can be translated to SI measures, and
later you can call it the way you wish. Like "1 GS means a change of 1V
during 1 second", as you have suggested, but many things are missing,
primarily where that voltage was taken from and how it corresponds to field
figures. Volt (if not V/m) is not a measure for fields, but, to say simply,
for wires. Not to mention the problem of the range of linear response Those
meters are very simplified devices probably reacting to induction made by
transients (and some frequencies) in a simple coil, in fact showing magnetic
field derivative - for a rather narrow band of changes...
I would appreciate others familiar with the measurements issue help me
convince you that although I don't deny GS filters could have some impact to
some people, such interpretation stories should not be diseminated by
serious people, who expect credibility, like you and I would like to be.
