How to deal with low voltage network ?

main reasons for failure

First a quick look at why a small voltage in the power grid, and then separately consider how to eliminate each of the fault.Thus, the main causes of low load is in a private home or apartment:

1. Insufficient cross section of the opening of the cable, an offshoot of the main power lines to your shelter.
2. Poor branch wires from power lines.
3. Improper connection of the circuit breaker in your introductory panel.
4. overloaded transformer substations serving.
5. Insufficient cross section of the trunk lines.
6. skew phase - the load on each phase of the transformer is uneven (for example, one phase is overloaded, the remaining underused).

This is the most common reason for very low voltages of private houses and apartments.As you know, the first 3 reasons apply only to you, and solve the problem have their own.As for the last three situations, they need to be addressed collectively, with neighbors, with the help of writing complaints to the appropriate authorities.Then we'll show you what to do to improve the self-stress and where to call to resolve the cause of the problem parent bodies.

Methods solutions

problems in the order listed reasons for the weak voltage in the network, we will also consider and ways to solve the problem.

The first thing that you should check out - if there is a weak power at the neighbors, or low voltage is only present on your site.If it turned out that the neighboring houses (or apartments) there is no problem, we start looking for the problem in your home wiring.

First you need to disable the automatic introduction and measure the voltage at the input.If he's here already below normal (GOST ± 5 and ± 10% of nominal - 230 Volt, ie 207-253 V), it is time to complain to the Energosbyt.If you enter a value in the match rules, and then connect the load voltage drops, Energosbyt nothing to do with need and troubleshooting their own hands.

According to the written above, it could be 3 if the voltage is low only for you.Start troubleshooting by checking the connection of the circuit breaker.If the upper jaw of poor contact with the wire, it may well be the cause of a weak tension.Visually inspect the machine body, if it is melted (as pictured below), it is necessary to replace it.Do not forget after the new circuit breaker to connect properly - properly tighten the wires to the terminals.

The machine is properly connected and there is no visible damage?Make sure that the wire cross-section of the opening enough for consumers in your house or apartment.For information on how to calculate the wire size for the power we described in the relevant article.The fact that veins voltage drop when connected with insufficient increased load section.

If the cross section of the cable home wiring enough, check as performed by an offshoot from the main line to your input.If it is twisted, then we can say with great confidence that the low pressure in the house due to poor wire tap.When poor contact resistance increases in the problem area, which entails a reduction in voltage.Even if a branch is made with special clamps, and check them too (the hull).You can also check out the clips by connecting the load - if this place will start to spark, or the clamp body starts to heat up - you need to replace the product.

worst things, if low voltage electrical network is not your fault, and the electricity supplier.In fact, to solve the problem in this case is quite difficult.Then we'll show you where to call and complain to solve the problem, and now provide a measure that will help to increase the tension in the home electrical outlet.

You probably know that the best way to connect a stabilizer, which may increase the value of 140-160 volts to the required 220. From personal experience I can say that this is the best option to fix it, becausemost of the voltage is low in the autumn-winter season due to the use of electric heaters.The stabilizer is not as expensive and can protect your appliances even if the overvoltage, which is also very important.If you have money, be sure to also purchase besperoboynogo power supply that can fix the problem in time, voltage drop, becauseoffline will supply electricity.Operate the emergency power system of 140 volts, which is great in this case.The only drawback - the high cost.For the model of the power of 5 kW will have to pay not less than 80 thousand. Rubles (price 2015).

stabilizer work is shown in the video:

Some experts also recommend to deal with low-voltage power supply using transformers or additional grounding, but we advise you to avoid such measures.The fact that the effects of such manipulations can be disappointing - surges up to 300 volts or a short circuit in the network!

Where to call and complain?

When the cause of a small voltage is insufficient cross-section of main power lines or weak power transformer in the substation, the situation is worse.On the modernization of substations and transmission lines need millions of rubles, so complaints have no effect, even if they write for years.However, you must still declare that dissatisfied with the quality of electricity to move the issue of reconstruction from the place.

If you do not know where to call and write a complaint at a low voltage in the network, it is advisable to read the following list:

1. Send a written claim to the electricity supply company.
2. If within 30 days after the registration of appeals no action you write is not going to attract Energosbyt help prosecutors, which also suggested to apply.
3. Rosprotrebnadzor.
4. city administration (district or village).
5. Energonadzor.
6. Public Chamber.
7. Court.

draw your attention to the fact that all of these bodies have their official websites which are not hard to find on the Internet.Not necessarily lounge around the wall and stand in the queues, you simply write a mail to the relevant authority that you have a low-voltage network, and that you have already tried to solve the problem with Energosbyt.It would be better if you present all available evidence in an email.

Another useful tip - when you write a collective complaint to the Energosbyt, refer to the GOST 13109-97, according to which the deviation from the 230 V should not exceed 10%.

Hopefully, now you know what to do with the low voltage network, where and to whom you need to complain to the fault eliminated!Once again we draw attention to the fact that the process of resolving the conflict with Energosbyt could drag on for a long time, so as soon as you need to buy a stabilizer, so as not burned all the appliances in the house.
