Low Voltage in Sockets: Impact on Meter Readings, 180V-200V Range, 600 Revolutions 1kWh Counter

Question

Hello, I wanted to ask if the low voltage in the sockets will not increase the meter readings?
How do they work?
1) current x voltage (constant 230V)
2) current x instantaneous voltage

Ordinary counter 600 revolutions 1 kWh

The voltage ranges from 180V to 200V.

Don't worry, voltage drops can't cause meter readings to overstate.
Are you sure about the correctness of the meter readings?
Have you checked multiple outlets to see if they all have the same voltage fluctuations?
If fluctuations occur only in a part of the installation, it should be checked by a specialist.
If, on the other hand, the voltage is the same in all sockets, then the fault is most likely with the power grid.
Either way, you should notify the power industry, such voltage drops should not take place and may indicate a fault.
According to the PN-IEC 60038 standard, the permissible voltage deviations from the nominal 230V are +/-10%, i.e. from 207V to 253V.

The fault may be in the network or in the receiving installation. Socket outlets are not a power supply point. You need to call an electrician who will first diagnose the installation.

Does your friend have noticeable flickering lights? Low voltage in all sockets and flickering light may be caused by poor contact of the PEN cable already in the connector before the meter. Troubleshooting: Have your electricity supplier check on their side of the property boundary first.

First, find the cause of such a voltage and do not worry about the meter.
Because the consequences of such a state can be more severe a few pennies more on the bill.
This voltage is below the limit value.

So low voltage is present in your friend's whole apartment? The standard says 230 +/- 10%, which is a bit low Regards

There is such a low voltage in all sockets. To measure the voltage, I use:

It works fine because in another house it shows 225V.
Renovation was recently and all cables replaced, but it's good that it doesn't inflate the bills

Thanks for the replies

It blinks quite often, I thought the bulbs needed to be replaced

zbich70 · Answer

I think it's better to check first own and make sure the sell is in someone else's . Only then question others. But colleagues proposing the opposite way of acting are right - after all, DSO does not charge for unfounded calls. So let's even call for a blown bulb and a non-contacting switch. And let's also call the water supply company for a leaking tap and a clogged toilet...

2ab92 · Answer

If it blinks, it means something is burning somewhere. If you have a multimeter, you can do a primitive measurement of the short-circuit loop impedance. Voltage drop / current drawn by some device of known power. You can find the current from the formula for power. This may lead to the failure site. But the best solution is to call an electrician with professional measuring equipment to locate the faulty circuit. This is no joke, it can end up in shock. Network failure - unlikely in my opinion, the neighbors would certainly notice.

It's messed up ... I'm checking with a meter if there is a short circuit and amperes drawn at the fuses and the socket.

pol102 · Answer

Just so you're aware that when you check the amperage before the fuse, you can blow the fuse in the meter or even the meter itself.
