Originally installation of the electric counter was optional measure for tracking change of indications of the electric power. But later time the utility companies have decided to make this condition indispensable. At the moment in each apartment there is metering device.
Electric meters: then now
During the Soviet period in each house standard counters with face value in 5-20 amperes and error in 2.5 were installed. On average, such device served the owner of the room about thirty years. Each ten years the owner of the room has been obliged to carry out intermediate inspection of the electric device. The interval between checks varied from 8 to 15 years, depending on counter model.
In Soviet period such characteristics for the device were considered as sufficient for stable operation of the electric metering device. But presently the person lacks one TV and teapot in kitchen any more. In the apartment there was set of the new devices giving huge load of counters of accounting of utilities. It both microwave ovens, and food processors, toasters and many other things, that is on the final result it is possible to say safely that in one room so many electric devices how many functioned in all apartment earlier work. Naturally, the counters calculated on twenty amperes which are not able to sustain such loadings. They were succeeded by devices with accuracy class in 2.0.
As in accuracy class between the new and old metering device the big difference, and the indications which are written off from them is visible too there will be distinctions.
Why it is changed
Replacement of the electric meter in inhabited and non-residential premises is done of reasons of own safety and also to lower cost of payments for utilities. The managing housing-and-municipal companies are engaged in direct replacement and installation of metering devices of the electric power. They under the law are subscribers who are obliged to provide good technical condition and appropriate protection to the operated devices and many other things. Even if the premises are owned, that is are privatized, the serving housing organization all the same has to replace the electric meter. Anyway, even if the apartment is rented, replacement of counters of accounting has to be made by the organization which is responsible for housing-and-municipal conditions of accommodation of all residents of the house entrusted to it. Therefore independent replacement of the metering device is inadmissible. For implementation of this procedure originally it is necessary to address to housing and public utilities with the application on replacement of the metering device. And the most important, installation of the electric counter of accounting it is favorable, first of all, to the owner of the apartment.
