Electric meters are currently installed in each apartment, office or office building. But sometimes when it becomes necessary to change the old meter with a new one, we go to the store and get lost on the abundance of models, not knowing what to choose.
In this article, you will learn about single phase meter from three phase, and how to choose a device that will suit your needs.
What are the counters?
So, any domestic electric meter is needed to measure the amount of consumed electricity for a certain period of time. The object of this measure is AC current.
Counters are known, are one — and three-phase – this is their main distinction. The first is used mainly for apartment buildings and private houses, garages, cottages, offices. They are suitable for power lines with operating voltage of 220 V and the corresponding frequency of 50 Hz. But three-phase meters set where the mains voltage is 380 To: for example, in large industrial enterprises. But you should know that these devices can support single-phase accounting, that is used in the voltage as 220 and 380 V. It is convenient for owners of large houses there installed power-consuming equipment (electric boilers, heaters, etc.). For this is the domestic three-phase meter.
In addition, these devices can be induction or electronic. Meters, using the principle of electromagnetic induction, are more common. They are fitted with rotating disc, unlike electronic counters, where such an element is a flashing warning light.
And, finally, the counters come in single and multi-rate. Very popular models such as the three-phase two-tariff meter. However, the feasibility of its purchase and installation, you need to count individually, because not in all regions there are system of differentiated tariffs.
