STETZERiZER® Microsurge Meter
The STETZERiZER® Microsurge Meter by Graham-Stetzer
is designed to separate the power line frequency to detect and respond
to low level high frequency voltages caused by transients and harmonics
on power lines. The level of these voltages is measured in GS
(Graham-Stetzer) units and will vary with electrical equipment and
loads. This device is recommended for use in conjunction with original
STETZERiZER® filters. The STETZERiZER® Microsurge Meter was
specifically designed as a companion to the STETZERiZER® Filters. The
meter measures the level of harmful electromagnetic "energy" present,
and its primary use is to guide effective STETZERiZER® Filter
installation. Patents Pending. All Rights Reserved.
Microsurge Meter Operating Instructions
The intellectual property behind the STETZERiZER® Microsurge Meter
belongs to the individual who conceived and designed the meter —
Professor Martin Graham. The STETZERiZER® Microsurge Meter:
Works for 60 Hz/120 Volt North American and 50 Hz/240 A.C. Volt European systems.
LCD display reads the Volts per second
present, which is an approximation for the high frequency energy. High
frequencies are the frequencies which are most harmful to equipment,
animals, and humans.
Is certified by the Government of Kazakhstan as the official means of measuring RF Energy on building wires.
Is simple to use — just plug the meter into any standard electrical outlet.
Conveniently lists the good, marginal, and undesirable range of meter readings on the back of the Microsurge Meter.
Electrosensitive people have reported sensitivities with readings as
low as 27 on the Microsurge meter. However, medium or even low
Microsurge Meter readings should not be interpreted as a guarantee that
there is no harmful health impact; only a medical expert can determine
that. Caution is required. Some harmful health effects of high frequency
energy on humans appear to be cumulative, and possibly non-reversible.
Science is inconclusive in this area, although the body of empirical
evidence available for guidance continues to expand and stabilize.
The STETZERiZER® Microsurge Meter measures the average magnitude of
the voltage surge (i.e. the rate of change of the voltage with time) at
the electrical socket. One GS Unit is 24 Volts per second. A human
having a low impedance to one of the terminals of the outlet (the
grounded wire) and a capacitive coupling of 800 picofarads to wiring
connected to the other terminal of the outlet (the hot wire) would have a
current flowing through them indicated by the STETZERiZER® Microsurge
Meter. The capacitance of two parallel metal plates that are one meter
by one meter and separated by one centimeter is about 800 picofarads.
The capacitance of a human to the hot wires will usually be less than
800 picofarads and the current through the human will be proportionately
lower. The current flow through the human will also depend on how the
capacitance of the human to the wire is distributed over the human. This
is important since it is the current flowing inside the body, and where
it is flowing internally, that determines the effect it will have on
the human. The frequency band covered by the STETZERiZER® Microsurge
Meter is about 10 kHz to 100 kHz. For complete specifications on the
STETZERiZER® Microsurge Meter, see U.S. Patent #6,914,435.
Microsurge Meter Design Criteria
Microsurge Meters were specifically designed 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
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 GS
(Graham-Stetzer) units (since no standard term is available). The GS
units are a measure of “harmful energy” which is a function of
frequency, or more generally, rate of change of voltage or dV/dt.
Using the Microsurge Meter for a Typical Home Installation
Microsurge meters measure the levels of safe, borderline, or
dangerous levels of “energy” present. These levels are conveniently
shown on the back of the meter for reference. These levels have been
developed through research (much of it in Russia and neighboring
countries) and confirmed by experience in North America. The levels have
been adopted by the Sanitary Stations (Health Departments) of the
Republic of Kazakhstan.
Starting from points that typically have the highest readings such as
the power input panel, computers, and televisions, the meter is used to
measure the initial levels of GS energy, and its reduction as filters
are added. Once the GS levels are acceptable at one location, the
process should be repeated at the next location. After the installation
of the filters is complete, a final confirmation of the GS levels should
be performed throughout the house.
