Electric meters are devices for accounting data on electricity consumption. In domestic plan, their owners win on smaller accounts for light, since regulatory tariffs are much higher than really consumed. In addition, modern counters offer cost accounting for different tariffs, depending on the time of the day, which also saves on electricity.
Types of electric meters.
There are two main types – induction and electronic. The former are the oldest and most reliable models, have a high service life and cost cheaper. But there are a number of shortcomings – a high accounting error, can allow you to pay less, or maybe, on the contrary, here is how lucky. The main disadvantage is the inability to use a lot of tariff regime that allows you to pay less. Well, the last minus is a low protection against hacking and wrapping indicators. Electronic counters are more advanced models, even with a lower margin of strength. Allowed to significantly save on electricity, due to increased accuracy of up to 0.5% and the presence of a multiple tariff grid system.
The parameters of electric meters.
The accuracy of the counter determines how much you will overpay for electricity. If old models had an error of two and a half percent, then modern should not exceed two. At the same time, electronic counters give out only a half percent of the error, which does not significantly affect the difference in electricity costs.
The multi -tariff meter represents to pay different amounts depending on the time of day and period of the year. You will pay less at night, and the same amount in the afternoon. In addition, various discounts, for example, on weekends and holidays, are also taken into account by counters.
The quality of your meter is determined by the inter -industrial interval, the greater it is – the better. The largest MPI indicators have induction electric meters. It depends on MPI when you should check the counter for serviceability and stability of the work next time.
Depending on the conditions of the installation location, you should choose your own electric meter model. If it is located in the house, then there is no difference in how it will be. If you are going to install the counter on the street, then it must withstand frosts up to 40 degrees.
