    It will turn off, but the impulse will go through the security and reach the receivers, won't it?

    Yes, but the timing of its operation also matters.

    Such a question for you.
    How to recognize zero and phase in a power socket?

    I carried out the measurements at the meter output, so there are only the power plant cables in front of it.

    Not necessarily - the ownership boundary may be elsewhere, you have it in your contract.

    Ok, there was no question, I removed the socket and checked the markings.

    Today, the voltages are better on 2 phases because it is 225, while on 3 I have noticed even 195 today, and currently it is still between 200-205v.

    So, for example, I have 200V in the bathroom and 225 in another room. Generally, I have to check whether it is always so low on this one phase or whether it changes.

    As for the cables, I measured it in the main box on the street and there are thick cables from the ground in black armor, so I found out that there are already cables from the power plant.

    Measurement of the phase-neutral fault loop impedance at various points should remove doubts about the quality of your installation.

    I thought so too, thanks Bronek for the information ;)

    In my opinion, the luck is weak. They turned it up to get the voltage at the lower limit of normal


    Heh hey, they always crank it up. In the past, on the control lamp, which also acted as a voltmeter, I had a voltage in the range of 205-210V ("red") on each phase. Currently, when I have a chance 50m from the house, the voltage is also "red" on the lamp, but in the upper range, i.e.> 250V :-D

    From the point of view of a distribution company, over 250V is better: more sales ...

    Hmm ... Can you elaborate on that?

    My colleague probably means that devices powered by higher voltage draw more power, at least some of them.

    Each equipment with the CE mark should be tested in the most extreme conditions, i.e. at a voltage of 253 V, which, however, does not change the fact that such a test takes only 15 minutes. Maintaining this high voltage for longer periods is detrimental to the equipment.

    Could this have any significant impact on the electricity bill of the average household?

    It may not significantly, but it will raise, not lower :D although I do not believe in the theory of tweaking the voltage for higher energy profits.

    In the case of too low voltage, e.g. 190-200v, does it not result in greater losses in energy transmission, which also translates into increased consumption?

    Probably the energy suppliers are in league with the producers of, for example, kettles to make them turn up the thermostats so that the kettles last longer ... :D

    ... and additionally with water producers to turn it up to the boiling point = 105 degrees :D

    And where did the idea come from that there was no reaction? Maybe the investment process of building a new transformer station is underway. Or maybe they just don't know about their friend's problem? The friend limited himself to the phone and let himself be disposed of. Dude Aksel, write a letter to the supplier and you will get a reply, then we will know more and maybe something will be clarified.

    Hello
    So far no one has come, if no one comes today, I will call tomorrow.
    Generally, here are the scams after the scam, so I would not be surprised if there was something wrong with the current. Recently, the CBA entered the commune regarding the sale of land for the estate. Ants like me can't do much :)

    Why? Since there is less electricity flowing?

    Somewhere on the net I read that the idea of increasing the voltage is to ensure less losses in energy transmission

    Col. aksel is correct. The higher the voltage, the lower the current and the lower the losses related to, inter alia, electrical resistance (P = I? * R). Devices can be damaged by overheating when voltage drops.

    Only that the situation you describe is in front of the transformer, not the end user. There, the voltage is converted into current and vice versa. In our case (at the end user), the voltage change is proportional to the current change.

    Take your word for it because I lack knowledge :)
    By the way, can such voltage surges, even if they are normal, i.e. 205-240, can damage equipment, specifically power supplies? Could anything get into DC through such spikes, something that could reduce the life of the equipment?

Topic summary

The discussion revolves around voltage fluctuations in a 240V network, specifically focusing on measurements taken by a user who observed dimming lights and varying voltages (200V, 215V) across three phases. The user inquired about the acceptability of these fluctuations, referencing a guideline that allows for a 10-15% variation from the nominal voltage. Participants clarified that in Poland, the standard voltage is 230V, with EU regulations permitting fluctuations of +10%/-15%. Concerns were raised about potential damage to LED lighting and appliances due to these fluctuations, especially following the construction of a nearby housing estate that may have impacted the local power supply. Suggestions included using a network analyzer for precise measurements and collaborating with neighbors to address the issue collectively. The conversation also touched on the responsibilities of energy suppliers and the challenges consumers face in proving faults in the supply network.
