from time to time in front of the owner of property raises the question of acquisition accounting devices.According to their testimony being the payment of benefits provided in the form of electricity, gas, heat and water.
power supply for residential single-phase circuit occurs, it corresponds to the structure of these instruments, showing how much energy is consumed tenants of the apartment or private home.It is measured in kilowatt-hours, which fully describes the nature of the goods, for which the payment.In kW, as we all know from school physics course, measure the power, and hours - the time from which it follows that the more power is consumed in this property, and the longer it takes, the impressive sum of the column "Total" on the receipt.
Previously, it was easier
Previously, single-phase electric meters in all were equal, round black ebony cabinet.Could a different current, which designed the device.The device has an internal mechanism with wheels, which were figures.Each turn of the previous decimal point causes the next one unit.Purchasing these instruments assumed the company offered to the public as required for normal energy.From earlier times remains the phrase "to pay for the light," but today the apartments electricity consumption is not just light bulbs, but also a variety of household appliances.
Apartment single-phase electricity consumption record only active power consumption.This is also a consequence of a long-standing situation in which the outlet include a spiral light bulbs and reflectors, in which the reactive component is missing, and the notorious "power factor" does not deviate from its unit size.
Eyes run
Today the situation is different.In the former Soviet Union, domestic single-phase electric meters almost not made, they often brought in from neighboring countries, and a major manufacturer of such equipment (and many others) became a people's republic with a very large population.In some cases, energy supplying companies recommend to buy one or another sample of the accounting unit, and the direction they are usually not the interests of the consumer, and some other reasons, among which can be and loyal attitude of the supplier to the replacement of defective products, andfavorable price for the seller.
How to choose?
single-phase electricity on the market in a wide range, and those citizens who have decided to purchase them on their own, faced with a choice.
There are, for example, multi-tariff instruments.This means that the inclusion of the energy consumed is conducted day and night in different ways.In some cities, to align daily consumption and reduce the peak load on networks tend to encourage people to include heating (for example, the "warm floor") only from evening to morning.There are such sophisticated devices more expensive than conventional single-phase electric meters.
price may depend on other parameters - for example, on the size of the maximum input current, measured in amperes.For residential apartments are usually enough 60 A, but is that the presence of a strong electric stove and the heating system increases this option and up to 100 A.
There is another important point - this information capabilities of the device.He may be on the remote control directly to energy supplying companies.While this innovation is not widespread, but it is expected that in the near future information on debt to pay for gas, water and electricity will be supplied directly to the enterprise servers, provide the corresponding service.Connecting single-phase meters to a single information system will greatly facilitate the payment process.
The rest of the range of the counter, as well as any other necessary things, motivated by value for money, as well as the advice of friends and acquaintances.
