It is estimated that many young friends are no longer familiar with the device of electric meters. Nowadays, they pay online and do not need to read the meter or check the meter from door to door. However, electricity meters are still our main equipment for measuring electricity consumption, but more people are not clear that there are many requirements for choosing electricity meters.


First, determine whether the line power you need to connect to the meter is DC or AC, and then decide whether to use a DC meter or an AC meter.

The meter is selected according to the connection method of the wire, and there are direct access and indirect access meters.

According to the needs of the function of your circuit to choose the corresponding electric meter, such as electric energy meter, prepaid electric energy meter and so on. Among them, the prepaid electricity meter can also be divided into coin or credit card.


Then make sure that you need to install all the negative power on the line. This is easy to calculate. You can multiply the power of all the electrical equipment on the line by its average use time and add them up.

Then we need to use the total power to calculate the total current. Normal power lines (single-phase circuits) correspond to 2 amperes per kilowatt of power, and three-phase four-wire circuits correspond to 4.5 amperes of current per kilowatt. For example, assuming that the total power of your single-phase circuit is 80 kilowatts, then the corresponding current is 360A.

There is no need to choose a large meter, because of the presence of transformers, you only need to select an equal value or a smaller meter.
