Diagnostics and repair of electricians in the apartment

Professional diagnostics of electrical wiring in an apartment is a suitable way to determine the level of safety of operation of the home electrical network with minimal costs. Our electrical laboratory engineers are ready to check the condition of the electrical system and provide a technical report. During the testing process, the compliance of the parameters of the power network, circuit breakers, sockets, lighting and other electrical equipment with regulatory requirements is determined.

When is electrical wiring inspection required?

Checking the electrics in an apartment with the involvement of qualified employees is advisable in the following cases:

• when receiving an apartment in a new building;
• after any electrical installation work;
• upon completion of repair or replacement of electrical equipment, individual elements or the entire electrical network;
• before taking over or renting out;
• if any problems occur in the electrical network;
• before buying or selling real estate.

An examination of home electrical wiring should also be carried out after its service life has expired. The technical report, compiled on the basis of the measurement results, is the basis for making a decision on the further operation of the electrical network and power equipment.

The service life of stationary household electrical wiring depends on the type and brand of power cables used. On average, it does not exceed 25–35 years. Specific data for home electrical wiring are specified in GOST 24183-80, PTEEP and PUE. If the service life has expired, but the electrical parameters meet regulatory requirements, the owner of the apartment decides for himself whether to replace the electrical wiring or continue to operate the old network.

Checking the condition of the electrical system in the apartment

Our company LLC “TsentrEnergoEkspertizy” checks the condition of electrical systems in apartments of any size, in the city of Moscow and throughout the Moscow region. During the diagnostics, the insulation resistance of each cable line is measured, circuit breakers are checked, RCD (residual current device) testing, grounding on sockets, lamps, household appliances, and the correct assembly and connection of the electrical panel is also checked, according to design and regulatory documentation. Based on the results of the inspection, we issue a full technical report for each cable line and equipment; based on the report, we can make a conclusion whether safe operation of the existing electrical wiring is possible or not or whether it requires repair or replacement.

Main identified problems:

1. The rating of the circuit breaker does not correspond to the cross-section of the cable line - this leads to the fact that when the load on the cable is exceeded, the circuit breaker does not operate, since it is designed for a higher current, which in turn is dangerous due to damage to the cable insulation and fire.
2. Faulty RCD or differential. machine - this leads to the danger of electric shock when touching conductive parts of electrical equipment, especially dangerous in the bathroom and kitchen.
3. Ungrounded sockets - this leads to the emergence of a dangerous electrical potential on the housings of electrical equipment, which is also dangerous due to electric shock.
4. The use of cables and wires that do not comply with GOST leads to damage to the insulation due to a short circuit, as well as overload of the cable line, which is a fire hazard.

Visual defects in electrical installations in the private sector:

The photo shows a floor electrical panel, in which everyone has a differential. automatic machines, except for one, which has a differential. the machine was replaced with an RCD, that is, a device that only triggers a leak, but does not trigger a short circuit or overload; such a violation caused a fire in the electrical panel. In addition, the outgoing lines from this RCD were made of cables that did not comply with either GOST or the nominal value, even if it were a differential. machine. At the same time, one of the cables was UTP, the second was PUNP (prohibited cable for laying), as well as an automatic reclosure powering single-pole circuit breakers, all under one contact clamp, which did not provide a reliable contact connection.

After the incident, the residents called us to measure the insulation resistance of their cables going into the apartment.

How to diagnose electrical wiring in an apartment in Moscow

Electrical network diagnostics includes the following types of work:

• checking all electrical wires and cables;
• Finding the section of wire where the short circuit occurred:
• current leakage detection;
• wiring breaks;
• reasons for the switch to trip in the electrical panel.

The most common electrical wiring problems are:

1. Wire breaks. It's not always a complete break. The wire may be only partially damaged, but this can lead to network disruptions.
2. Current leakage is a common problem in old wiring.
3. Defects in wire connections can lead to a fire in the wiring.
4. Grounding failure.
5. Insulation failure.
6. Damage to protective devices.
7. Phase imbalance.
8. Power failures.

When diagnosing electrical wiring, our technicians will check the compliance of the components and wires with the wiring diagram. If the diagram is violated, it is necessary to reinstall the wiring in accordance with safety requirements.

When carrying out work, our company’s specialists check the operation of all wiring components, determine the power and maximum load.

Our task is not only to fix problems, but also to configure all wiring elements.

When is electrical wiring diagnostics needed?

Checking the electrical network is mandatory

if there has been
a short circuit
or
power surge
.

In the event of an emergency, our company’s specialists will conduct a comprehensive inspection.

But even if nothing happened, no one is immune from problems with wiring in the future. A routine check will allow you to detect and eliminate the problem at an early stage.

Urgent external inspection is necessary in the following cases:

• Unstable operation of the electrical network: blinking lights, malfunctions of electrical equipment;
• frequent shutdown of the machine;
• weak power grid;
• the wires heat up;
• burnt smell of insulation material.

The reasons for these situations can be very different:

1. leakage current;
2. short circuit:
3. voltage fluctuations;
4. wiring wear.

In all cases, immediately call an electrician to diagnose the wiring and fix the problems.

Diagnostics of electrical wiring in an apartment in case of flooding

Diagnostics of electrical wiring in an apartment in case of flooding of the apartment by a neighbor on the top floor.

• We use special equipment: a wall moisture meter. You will be able to technically confirm flooding in your apartment and thereby find out the reason for the lack of light in the bathroom or kitchen.

Electrical wiring diagnostics: comfort and safety for your home

Qualified electrical wiring diagnostics in the shortest possible time, 100% accuracy, prompt troubleshooting

The power grid provides a great service in solving various everyday problems, and its malfunctions inevitably affect the comfort and business routine of the day. Therefore, it is worth taking care in advance to ensure that the network functions without interruptions, and that each electrical appliance remains ready for use for as long as possible.

1. Problems that professional electrician services can help prevent:
2. Network congestion due to the use of a large number of electrical appliances
3. Loss of electricity due to chronic wiring faults
4. Risk of short circuits
5. Failure of frequently used household appliances
6. Unjustified waste of money on local troubleshooting and the purchase of new equipment for the home.

We suggest you use the services of qualified personnel, saving yourself from the negative consequences of problems in the electrical network.

What work is carried out during wiring diagnostics

The functioning of household appliances in the house depends on the correct operation of electrical wiring. Diagnostics is necessary if you notice the following violations:

• short circuits occur;
• Electrical sockets are not working properly;
• traffic jams are knocked out, circuit breakers are triggered;
• the light turns off.

In these cases, you need to urgently call a technician to diagnose the electrical wiring in the apartment. Without appropriate education, you cannot work with electricity yourself, as it is life-threatening. Muguru masters live in Moscow, so they will come to your home quickly, within an hour.

The specialist will bring with him the necessary equipment for diagnostics. The work is carried out in several stages:

• inspects electrical wiring, distribution panels in the apartment and on the site;
• using a special device, finds the damaged area;
• determines the specific location of the electrical wiring short circuit;
• establishes the reason for the response of the circuit breaker;
• inspects the site of damage or current leakage;
• finds the location of broken electrical wires;
• Troubleshoots problems to ensure efficient operation of electrical equipment.

All Muguru masters have documents confirming their qualifications. During diagnostics, they strictly follow safety rules when working with electricity.

Wiring and requirements for it

The first and very important point that you should know about before starting electrical installation work is that in panel houses (Khrushchev-era buildings) you most often cannot trench walls in accordance with Moscow Government Decree No. 73-PP dated February 8, 2005 “On the procedure for renovating premises in residential buildings on territory of the city of Moscow." Also, according to Government Decree No. 508 (Clause 11.3 and 11.11 of Appendix No. 1), it is prohibited to tap load-bearing walls.

In this case, it would be rational to conduct wiring through existing channels, the floor or under the ceiling (if a suspended or suspended ceiling is planned). The first and last options are more preferable. If the electrical wiring in the apartment is changing and you plan to cover the walls with plasterboard, an excellent solution would be to lay the wiring behind the plasterboard.

Important! It is strictly prohibited to scratch the ceiling in the apartment! The only option in which you can make grooves on the ceiling is to first apply an additional layer of plaster to the ceiling, in which the cable will be hidden. This layer can already be carefully grooved without touching the monolith

Those. The simplest option is to draw lines from the panel to the sockets and switches along the ceiling, ducts or floor, and then make vertical grooves and so-called wells for installing socket boxes.

Another important point that you should pay attention to if you decide to do the wiring in the apartment yourself is that noisy work is allowed from 9 am to 7 pm (except Sundays), while an hour of silence must be provided from 1 pm to 3 pm! Shredding is a noisy job and can not only cause the anger of neighbors, but also cause a fine (from 1 to 5 thousand rubles for individuals)

Let's return directly to the installation of apartment electrical wiring. As we said earlier, the length of the conductors must be purchased with a reserve. This reserve will be used to connect them to each other (on each side the outer sheath of the cable is removed by 5-10 cm) and to connect sockets, switches, lamps (the length reserve is from 10 to 15 cm).

The video shows how to correctly install electrical wiring in an apartment without breaking the rules:

What is included in the electrical installation inspection work?

During a complete inspection of the electrical installation, the following is checked:

• Availability of protective equipment, timing of their testing, conditions of detention. Energosbyt inspection inspectors first pay attention to the availability and timing of testing of protective equipment. All instruments located in electrical switchboards must also be verified;
• Compliance of the electrical installation with single-line diagrams and design documentation. During the operation of an electrical installation, changes may occur, as outgoing lines and protection devices may be added (or removed). Existing and designed protection devices, types of cables and wires used are verified. The need to install RCDs on outgoing lines is determined;
• Calling outgoing lines from circuit breakers of group and distribution boards. In case of changes in the circuits, as well as the absence of marking of outgoing lines in the switchboards, the area of ​​responsibility (what it turns off or what it is responsible for) of each circuit breaker in the distribution switchboards is determined;
• Carrying out a set of tests of electrical equipment with the preparation of a Technical Report and a list of defects (if detected).
• Drawing up single-line diagrams of electrical distribution boards as part of an electrical installation. Based on the results of the survey, a single-line diagram of each electrical panel is drawn.
• Drawing up plans for the location of equipment: location of electrical panels, location of electrical sockets, switches, lamps, etc., routes for laying cable lines of supply and group lines.

Partial inspection of electrical networks is carried out if it is necessary to troubleshoot in individual areas, clarify consumer groups, loads, etc.

Diagnostics of electrical wiring in an apartment and the cost of the service in Moscow

Diagnostics of electrical wiring (electrical network)
is the most important stage of repair work in the house.
If problems are discovered in the network after repairs, it will be necessary to provide access to the electrical wiring, and for this you will have to ruin the new wallpaper. That is why all work related to electrical wiring must be carried out in a timely manner.

At the same time, a complete replacement of the wiring during repairs is not at all necessary if it has already been changed and there are no complaints about its operation. However, if your house in Moscow was built more than 10 years ago, it makes sense to think about completely replacing the electrical network in the apartment.

Attention!

Under no circumstances should you check the electrical wiring yourself. If the test is carried out by an unprofessional electrician without permission to work on the electrical network, then he can not only damage the wiring, but also risk his own health and even life.

How to identify problems

Wiring Diagram
Troubleshooting is easier if you have a basic wiring diagram. The plan is attached to the technical passport of the housing. If not, a drawing is drawn up - if the rules are followed, the routes run in a straight line (vertical, horizontal).

Regular testing with a multimeter will help identify problems. It is not difficult to determine in which area the breakdown occurs. For example, if the sockets and switches connected to the box do not work, the problem is here. If there is only one, there is a breakdown between the box and the socket.

Modern technologies and systematic checks will ensure safety during operation of electrical wiring in the apartment and increase service life. The main thing is to follow the principles and rules of work.
