How to take readings of an electricity meter

Life can not be turned back, the counter can be stopped. Infinitely ready to look at the resourcefulness of people doing in two accounts. In order for the night to come to take the testimony right authorized bodies, we do not recommend to mess around with the counters categorically. It’s about saving - it’s easier to buy the right light bulbs. More profitable to take LED.Save up to 90%.Today we are talking about how to take readings of the electricity meter.

Electricity meter readings: what we measure

Look at YouTube: a device called Econor saves up to 50% of energy. This is hardly true - the device performing the work is powerless to do the same for less money. We understand that there is the concept of reactive power, it is permissible to exclude a factor from the counter.

Here is an intelligent thematic note zametkielectrika.ru/electricity-saving-box-eto-obman-i-razvod/.The man explains: when connecting curious devices, reactive power is saved. It is produced by correcting the phase shift with a conventional capacitor. Home counters do not take into account the reactive component. It does not bring benefits, it expresses losses. At substations, you can find compensating capacitor blocks like UKL( P) - 56.

Substations spend energy on the released reactive power. Indeed: Econor saves energy, state. Expressed vars. Indirectly to blame the consumer. The load forms a coefficient due to the presence of reactance. The duties of the manufacturer include the introduction of compensators in the equipment.

Pay a couple of thousand for Econor is unacceptable. Can the price of auxiliary devices be compared with the main equipment? The author of the note above showed: the reactive component of the power, compensated by Econor, is 100 VAR.Simple inhabitants - enough. But the counter counter strife. Some consider VAR, are charged separately.2-tariff meters are indifferent to losses.

. As conceived by the state, it seems that the plants should compensate for the inability to reduce the reactive load of the circuits. We take the risk to assume that it is possible to install solid sizes of compensators that save government goods. Ordinary citizens are not concerned with the question.

disk. It is important to be able to take meter readings correctly, to understand what we are measuring. The main question is to understand what the metering device is doing. State standards will help to answer( GOST 25372).Look at the presented photo, adorn the record: 600 revolutions of the disk are 1 kWh. This only indicates: the active power is measured( see table 2).According to the document, it can be seen: the total power is measured in VAh, reactive - varh.

In the marking of electric meters there is a link to the measured parameter. Letter designation like the one above. In this case, the total power is called apparent. We will now give an explanation of the fact. An electricity meter measures a complex number, one component of which is imaginary.

Considering how to evaluate testimony, understand what you need to submit to managing organizations. In the case of ordinary citizens is taken active power, measured in kWh.

Read the scale of the electricity meter

Many devices have no decimal place, you need to rewrite 4-5 digits. Residents are concerned about the question: suddenly the scale overflows. The readings of the electric meter after 9999. .. Savvy, they say: the numbers will be reset. The drums are round, why not just go on the next cycle. After nine, of course, it goes zero, so the score will be 0000.

Let's pay attention to readers: for the most part, the readings of the old-fashioned electricity meter are presented in two ways.

1. Scale implies: the fractional part can go after the comma. Many are confused by the fact: the first is a different color. We do not know, but the fact remains that after the comma the fractional part. Not important character drawing. Comma, point - all one. The sign that defines the beginning of the fractional part of the meter reading.
2. In the picture above, the electricity meter is different. Here the fractional part is expressed by the arrow. It moves counterclockwise, even the markings that go around indicate. Since the numbers are 5, there is no danger of overflowing the scale( 40000 kWh, running for more than 30 years of operation of the device).

We believe that special skills do not need to take readings. We add that sometimes there is no comma, just the fractional part( or only the first digit) is highlighted in color. Many, we believe, are tormented by the question - is it possible to stop the readings of the electronic meter? We recommend to equip the house with LED lights( Chinese) instead of Econor. See benefits:

• Wiring less heated. In order. The difference in power consumption is 10 times.
• You can choose the color of LED bulbs, helps the body to tune in to the correct work cycle. Cold tones are appropriate during the day to create a mood for vigorous activity. Warm - conducive to falling asleep.
• LED lamps are bright due to homogeneous radiation( if you can put it).The spectral density is concentrated in a small area, causing the addition of waves. The incandescent lamp gives a weak interference pattern, part of the oscillations is extinguished.

On top of that, let's say: you need to choose LED bulbs using a poor camera tuned to the shooting mode. Be sure to focus carefully, see if there is any blinking. If there is a flicker, the LED bulbs return.

Modern electricity meters

To take readings of a two-tariff electricity meter of modern production, you will need to read the instructions. The devices are equipped with a liquid crystal display, the ability to set the billing by time of day, measure the cosine of the loss angle( the angle between the active and reactive powers of the vector diagram).Fresh models measure the temperature. Note that optical, serial ports, and wireless communication are used for programming. There are models with a USB-plug.

The load control relay is included in the electricity meter. The device will allow dividing consumers at home into important / non-important ones. A part can be switched off automatically if suddenly the total power consumption exceeds the tolerance. It is important for private houses, each quota is allocated. In order not to jump over it, an introductory machine is put in, the owner will be carried away by spending, just cut down the food at home. You need a long, tedious understanding that went awry. A multi-tariff electricity meter will allow you to realize your plans. There is a main conclusion, where important consumers are planted, the rest goes to the secondary.

electric meter. Charging is not allowed by the hour - by day of the week, by type( holidays, weekends, weekdays).The instrument is programmed by the proper person, the work is carried out under supervision, the device is sealed. The readings are scrolled through with a single button that is pressed many times in a row until the desired value appears. Indications are provided in physical units( kWh, for example), economic( ruble).Determined by type of counting mechanism. Approximate assignment of display symbols:

1. The letter A usually indicates active power. In combination with this symbol, the numbers of tariffs can be displayed on the screen( according to days: weekdays, holidays).The numbers of the plans are indicated by numbers, and the very fact of the presence on the screen is the letter T.
2. . The reactive power is denoted by the letter R. And there are forward and reverse directions( reflected in the network).There is an opportunity: the state plans to introduce a program like the European one, where it is planned to pump solar energy into the network from each subscriber. You can earn.
3. Temperature, date, current time are working parameters, can be displayed by display.

Switching is performed on the ring. The order of the display parameters is specified in the instructions. It is most convenient to immediately read the total raid on tariffs, electricity meters provide an opportunity. In our example, the mode where T1, T2, T3, T4 are highlighted simultaneously. Individuals pay for the active component of power, the figure should be oriented. Marked in addition to the letter A through R.

. When you need to take readings, simply press the control key until the desired numbers appear on the screen. Some electricity meters give the amount in rubles. It is assumed to deduct from the previous testimony. Traditionally, it is measured in the third decade of the month, depending on the region. To take readings of a three-phase electricity meter of the modern version, it would not hurt to read the instructions. The control is carried out in a similar way, active, reactive powers are measured for each phase, there is a possibility of billing. After programming the device is sealed.

The old electricity meter is easier to use, probably safer, the new ones are focused on the state’s attempts to bring order to the sphere of consumption of services at the expense of citizens. We believe that after a fixed time attempts will be made to register the consumption of reactive power, many will be forced to build instruments like Econor. The scheme is so simple, widely known, that more people would prefer to assemble it by their own hands, will certainly cause an increase in demand for capacitors in the country. We hope that readers now know what numbers to watch, what the last digit on the counter means.
