What is the difference between a three-phase electric meter and a single-phase electric meter?

There are two types of electric meters, one is a single-phase electric meter and the other is a three-phase electric meter. In fact, what is the difference between a three-phase electric meter and a single-phase electric meter?

The function is different

Single-phase electric meters generally intelligently measure active power or reverse active power, and their functions are relatively simple compared to three-phase meters.

In addition to measuring active electricity, three-phase electric meters can also measure reactive electricity. The functions are convenient. Three-phase electric meters and single-phase electric meters are much more complicated.

Different scope of application

Three-phase electric meters are generally used in places where the current is relatively large, such as factories, government buildings, villas, shops, etc. These electricity demand is relatively large, so three-phase meters are the best choice, and three-phase meters can also add mutual inductance. Therefore, a three-phase electric meter with a transformer does not have a maximum current. As long as the ratio of the transformer is sufficient, the current can be as large as possible.

Although single-phase meters can also be of mutual inductance type, most single-phase meters are still direct-entry. As long as they are suitable for rental houses, hotel apartments, etc., direct-entry meters also have requirements for the maximum current. If the maximum current is exceeded, the meter Will be burned out.
