Sine wave is clean, the spiky line in the middle shows dirty frequencies
Fluorescent light, dimmers and other electronic equipment connected into our circuits create voltage frequency fluctuations, which are often called 'dirty power', or 'dirty electricity'.
There is mounting evidence that the messy noise they create can interfere with our health, causing sleeping problems, fatigue, allergies, and cancer.
See the brilliant summary by Mikko Ahonen.
The common global electricity and supply grid resembles a large inland water. All pollution from the feeding rivers empties into this great lake and from this lake we are all being supplied. This analogy should demonstrate how polluted our supply grids are. -
Switching power supplies, thyristor and phase angle controls, IGBTs and many power semi-conductors are switching within milliseconds and create large energy fields with harmonics and spikes of up to 10.000 V.
This power does not simply disappear, but gets transported through the power grid over great distances. They massively affect every power plug in homes and subsequently the connected consumer loads (like radio, TV and computers).
Large energy potentials are also forming E- and M-fields. These interfering voltages can be measured and established while grid-bound or as emitting interferers according to EN 55011…22.
Many people are sensitive to these influences and show corresponding symptoms.
Our Alpha series was specifically designed for this area of application and attenuates even in the lower frequency range - where all clock frequencies are created - and effectively dampen any significant interference above the required 50 Hz mains supply.
It filters the frequencies of <10kHz bis >30MHz.
