Dirty Electricity - Introduction
We are living in an increasingly complex electrical environment and are inundated daily with electromagnetic frequencies ranging from less than 20 Hz (electric trains) to greater than 1 billion Hz (wireless telecommunication). Most of these frequencies are man-made and were
not present until the invention and subsequent commercialization of electricity (early 1900s), radio (1920s), radar (1940s), television (1950s), computers (1970s), and cell phones (1980s). Whether, and at what intensities, these frequencies have biological effects has been a subject
of scientific debate for decades.
The present paper is restricted to the electromagnetic spectrum associated with the distribution of electricity and the poor power quality that results from electronic devices that generate high frequencies and transients that ride on top of a normal 50/60 Hz sine wave. Graham/Stetzer filters are able to improve power quality by reducing microsurges [refer to website for definition, www.stetzerelectric.com] in the frequency range of 4 to 100 kHz on
electrical wiring. This paper documents the response of individuals to the removal of dirty electricity in their home or work environment. Five case studies are presented. They include
a healthy individual; a person who has symptoms of electrical hypersensitivity; a person with multiple sclerosis; one with diabetes; and the response of 18 teachers and their students to improved power quality in their school.
