What can be done with unstable voltage in the network (which stabilizer to choose)?

Question

Iron

In general, the situation is simple in the area where the parents live, there is a very weak electrical substation, because the voltage in the network very often drops to 160V. This affects the operation of equipment very badly: the washing machine and the water pump may not cut in at all, the Internet router hangs, the computer reboots, etc. It is clear that for one computer you can buy an uninterruptible power supply with a built-in stabilizer, and for the rest of the equipment separate stabilizers - but it seems to me that this is a worthless decision, it is too expensive to buy such a number of stabilizers. I would like to buy 1 powerful device and put it at the entrance of the electrical network to the house.
If you have encountered such a problem, tell me how you solved what equipment you used. I would also be grateful for links with information on solving such problems.

Answer 1

You need to buy a thyristor stabilizer.
In no case do not buy a mechanical stabilizer (there is a moving contact inside that slides along the winding). All sorts of Resanta, etc. it's all shit (verified).
Look at the Russian Progress stabilizers (we have had this one in a private house for 2 years). There are no complaints.
All stabilizers are marked for VA power (volt * ampere). This means that the stabilizer can develop the following maximum power W = stabilizer power / 220 * mains input voltage / sqrt(2)
Choose power with a margin of 20-30% of the maximum in your home. You can increase the stock, because. there is a tendency to increase the power consumption of devices (read before there were 500 W irons, now 2 kW each)
Install the stabilizer in a secluded place, because. there are fans, they can hum, and the stabilizer itself hums.
Also consider grounding the stabilizer, and grounding all devices in the house too.
When buying, also pay special attention to the method of fixing the wires inside the stabilizer. These should be bolts on which you can "wind" the wire. You should not take such a stabilizer, the wire into which should be inserted (through a hole) and clamped inside with a bolt, because. such a connection is not reliable, the bolt can loosen and the connection can get very hot (we had a flame like this, we saw it well in time).
Also pay attention to the operating range of input voltages. It is better that it be wider, in your case from 120 V to 250 V, because. you never know what will happen in the future, and the wiring in the villages has not been changed for 30 years.

Answer 2

Somehow it seems to me that a large stabilizer will cost you more than several small ones, take the same washing machine, it is probably 3 kilowatt hours in terms of power, not to mention irons, tiles and other powerful things.

Answer 3

I wonder which stabilizer to choose if the voltage jumps all the time and sometimes you need to connect a welding inverter through it?
