When we talk about clean power we are referring to how perfect the Sine Wave is. How much distortion is being caused by harmonics? What the total harmonic distortion (THD) is. The IEEE (Institute for Electrical and Electronic Engineers) has standards for THD which can be found in the IEEE 519. The basic, short version is that standard power that is supplied to your home will have no more than 5% harmonic voltage distortion with the largest single harmonic being no more than 3% of the fundamental voltage. If you are shopping for inverter generators this is sometimes mentioned as a selling point if they have really low THD. Inverter generators have other issues as described in this blog post. What the Microsurge meter does is quantifies the THD in your home by analyzing what frequencies are present in the THD. If you have an oscilloscope reading, then you have a much better break-down of which frequencies you are dealing with that make your THD.
On this page you will be find many before and after pictures of graphs that show a reduction in frequencies on the building wires after installing Stetzerizer Filters. The frequencies that are reduced or eliminated are the ones that range from 4 kHz to 100 kHz (which the filters are designed to filter because they are biologically active frequencies). People who are electronically sensitive will react to this frequency range on a building’s wires. You can find these frequencies in almost every building in America; the only exception being those buildings that have filters plugged in. These frequencies are created primarily by the electronics that we have which include but are not limited to: switch mode power supplies, computers, certain light bulbs, variable frequency drives, game consoles, Blue Ray players, and generally anything that uses a non-linear load. Non-linear loads are pretty much found in all the electronics and ‘green items’ that you have in your home today.
The first step in dealing with any problem is getting a measurement of how bad it is. Measure first to find out what your levels are. To do this, you will need a device like the Microsurge Meter. The higher the number on this device, the worse it is. To reduce this number you simply plug in filters where you need them (you will not need one in all of your outlets).
