Electric meters are divided into two major categories, one is a single-phase meter and the other is a three-phase meter.

Is the sensitivity of a three-phase meter higher than that of a single-phase meter? In fact, it is not entirely true. The sensitivity of an electric meter is determined by the accuracy. The higher the accuracy, the higher the sensitivity. As for whether the three-phase electric meter is more sensitive than the single-phase electric meter, it depends on the model of the three-phase electric meter, simple and effective. Electronic three-phase meters are generally accurate to level 1, or even level 2, and single-phase meters are accurate to level 1, so the sensitivity of such three-phase meters and single-phase meters is the same.

There are differences in functions: single-phase 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 power, three-phase electric meters can also measure reactive power. The functions are convenient. Three-phase electric meters and single-phase electric meters are much more complicated.

The scope of application is different: 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 electric meters are the best choice, three-phase electric meters It can also be used with a transformer, so a three-phase meter with a transformer does not have the maximum current. As long as the transformer ratio is sufficient, the current can be large. Although single-phase meters can also be of mutual inductance type, most of 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.

The wiring method is different: three-phase meters are divided into three-phase three-wire meters and three-phase four-wire meters. There are 10 wiring holes on the three-phase meters, and the wiring is simpler than single-phase meters.
