New Critical Problem with ‘Smart’ Meters: The Switching-Mode Power Supply (SMPS)

It’s now becoming more widely known that microwave radiation is not the only type of radiation from smart meters that is causing illness.

Just when you thought you had mastered all the esoteric acronyms, and all the problems with ‘smart’ meters, here’s one more: Switching-Mode Power Supply or SMPS. This new element in the ‘smart’ meter controversy deserves immediate full official and public attention.

In our on-going investigation into why so-called ‘smart’ meters being installed against rising public opposition are causing so many people to be sick, and so many problems with other electric and electronic equipment, we have been fortunate to obtain the advice of electrical engineers.

On examination of typical meters, including ABB, GE, and Landis Gyr, they report that, in addition to its RF transmitter, each wireless digital meter also has a component called the ‘switching-mode power supply’ (SMPS) – switching power supply for short. Its function is to ‘step down’ the 240v alternating current (AC) coming in from the utility pole power lines to the 2 to 10 volts of direct current (DC) required to run the meter’s digital electronics which record the electricity usage data.

The SMPS function emits sharp spikes of millisecond bursts constantly, 24/7. The SMPS on the OWS 514 NIC model, for instance, which is the smart meter model widely installed by PG&E throughout its territory, has been measured to emit spikes of up to 50,000 hz and higher. This constant pulsing of high frequencies, in addition to the RF function, is causing not only interference with other electric and electronic equipment in many homes with smart meters installed, but also is causing havoc with biological systems in its field of exposure.

Dirty Electricity
When current flows through the wiring of a building it generates a surrounding electro-magnetic field that radiates outward all around the wires at right angles to the direction of the current’s flow and reaches out into the room.

It is well known that switching power supplies can generate spikes of so-called electromagnetic interference (EMI), or high frequency transients, which then travel along the wiring in the walls, radiating outward in the wiring’s electromagnetic field.

Such spikes are known as ‘dirty electricity’ and can be conducted to a human body that is within the range of the radiating field. This function is on all smart meters used by all utilities and is on constantly, 24/7.

One of the engineers explains it this way:
“Extensive measurements have demonstrated that all of the meters measured so far, including ABB, GE, and Landis Gyr, emit noise on the customer’s electric wiring in the form of high frequency voltage spikes, typically with an amplitude of 2 volts, but a frequency anywhere from 4,000 Hertz, up to 60,000 Hz. The actual frequency of the phenomena is influenced by the devices that are plugged into the customer’s power. Some houses are much worse than others, and this observation has been confirmed by PG&E installers that have talked to us.”

Another Fatal Flaw in ‘Smart’ Meters
It is this ‘dirty electricity’ generated by the e-meters’ switching power supplies that is a major contributor to the symptoms being reported by growing numbers of people in association with the e-meters thus far installed.

    Watch a demonstration of the frequencies put out of an Arizona, USA smart meter at this link.

  2. Sharon says:

    Dirty electricity is not a problem associated with smart meters only. Any digital meter will create dirty electricity because it runs on electricity which must be converted. This is another reason why we all must fight to keep our analogs.

  3. Sharon says:

    All digital meters (non-analog) run on electricity and create dirty electricity, so don’t think that this is a smart meter problem alone. This is one more reason we should demand to keep our analogs.

  4. Take Action Now says:

    So what can I do to have my Analog meter returned?

    Am I able to legally have it reinstalled.?

    Are there any manufacturers of the analog meter that we can contact to have this installed?

    Is it possible to set up a class action against the who is reaponsible for this. I am guessing the legal profession is going to get paid on this as it will come down to politics?

  5. Adam says:

    Switch mode power supplies are one of the most common power supply types. Every computer and laptop thesedays uses one, along with mobile phones, battery chargers etc…

  6. Robert Scott says:

    Just about every piece of electronic equipment used in your homes now days uses a SMPS, very few use a conventional power transformer. For instance all televisions and have done for the last at least 20 years, computers all use a SMPS and have done since their inception. By replacing the heavy and expensive power transformer, appliances with SMPS the instrument or electronics equipment can become cheaper because the low frequency transformer has to be wound on iron laminations and can be labour intensive. Most SMPS reside in a shielded metal box so any leakage RF is contained as it would be in a Faraday shield cage.
    So stop taking the words of an inexperienced so called engineer as they know diddly squat about the real world of electronics. Only in some sensitive instruments like sensitive radio receivers are power transformers still used. The RF radiation (not micro wave radiation) would not extend much beyound the equipment itself.

  7. TL says:

    A couple of points of clarification are required:
    1 These SMPS bursts are present even when the communications card is absent or deactivated, correct? So it would be of little comfort for someone having a non-communicating smart meter forced upon them to say, “Well, it’s not emitting radio frequencies”.
    2. Do we know if these SMPS bursts account for some of the up to 190,000 bursts ( that smart meters emit each day, or are these two completely different matters?

    • Let's get real about RF says:

      1. Yes, as other responses have noted, any digital meter (communicating or not) creates ‘dirty’ electricity (ie harmonics and transients). And there are a whole load of other things doing the same! The IEEE (Institute of Electrical and Electronics Engineers) said in 2011 that “Harmonic pollution is a growing problem caused by the widespread use of power supplies and other non-linear loads. It can result in power loss and equipment damage and it may also be related to environmental safety issues.” How much worse must the problem now be??
      2. The “Quantifying Smart Meter RF EME Levels in Victorian Homes” report focused on measuring the microwave RF pulses from smart meters (so higher up in the spectrum). This is a different issue. You can read the report if you follow the links through on the post that you gave.

      The 190,000 relates to wireless “bursts” and not SMPS.

      I’m not sure whether “bursts” is a really correct term when describing the “high frequency voltage transients” (otherwise known as “dirty power” or “dirty electricity”) on home wiring. This is because when dirty power is present on wiring it is a constant spiking without interval.

      SMPS “bursts” will still be present on any digital meter regardless of whether it is a transmitting meter or not. The activity relates to the conversion of AC power to DC power required to operate the meter itself. I believe that a wireless transmitting meter will have more electrical activity within it than a non transmitting meter. I would say that the greater the electrical activity within a digital meter,,Furthermore the 190,000 wireless bursts themselves also get onto the wiring in dirty electricity form. So any digital meter will produce dirtythe greater the amount of SMPS dirty electricity. Thus any digital meter will place dirty electricity onto home wiring but a transmitting digital meter will not only place more even dirty electricity onto home wiring but also dirtier dirty electricity. This dirty electricity not only gets onto your own home wiring but it also gets into the grid itself and thus onto the wiring of neighboring houses as well.

      Dirty electricity present in wiring behind bedheads causes headaches. This was my own experience. Removing the dirty electricity from the wiring in the house but especially behind the bedhead will cause the headaches to gradually ease off and cease. I proved this by several different means and methods.
      1. Switching off all my power at the mains.
      2. Switching off completely and permanently the circuit breaker for the circuit that incorporates the wiring behind my bedhead
      (also muffling the dirty power on the rest of the circuits in the house through filtering)
      3. Utility company disconnection of power from neighboring properties having smart meters (for non payment of accounts)

      These three methods all gave me relief from unending debilitating headaches.

      Each of these three methods were exercised in conjunction to the effectual shielding my house from the wireless transmissions of surrounding property smart meters as confirmed by a hand held radio frequency transmission measuring device.

    What good does a comment do. Australia is not involved in politics…NONE. It’s all pretense……We might stall them with this nonsense but they’ll get their way in the end. WHATS THE POINT.

    • Aldo says:

      It only takes one person to take a strong stand that can achieve much. If you choose to just roll over and die, then you are dead. It’s THEN that they’ll certainly get their way.

  9. andrew whitney says:

    We still have our original analogue meter with a padlock on it. Let’s all fight on, never give up and keep the pressure on. There is so much evidence now globally from experts in the medical, scientific and environmental fields that the government will be forced to act. Instead of people being forced to have smart meters, the government will be forced to remove them. Never, never, never, never, never give up as a bloke in a bowler hat once said.

    • Andrew Samman says:

      We too still have our analogue meter locked up in the meter box with a CCTV camera watching it.

    • Happy Dissenter says:

      Agree 100 % with you Andrew. I’ll never move house into one with a smart meter. They will have to carry me out in a box.

    SMPP is just lazy, they should have a transformer. I know all about this rubbish because I play guitar, and it makes everything buzz like crazy using single coil pickups. I would take a hammer to this if it was in my power
