According to the power supply method, a 100A energy meter can be divided into a single phase 100A energy meter and a three phase 100A energy meter. These two meters are also commonly used in our daily operations and lives.
single phase electricity meters are mainly used for residential users. 100A electric energy meters are relatively less used in residential households. Generally, household power consumption is far less than 100A. The use of 100A electric energy meters will cause a waste of resources. In general, residents choose to use 60A or 40A electric energy meters of the time. With the improvement of living standards and the increase in electrical appliances, 100A electric energy meters will become the protagonist in the future. There are many three phase facilities in the commercial building sector, such as elevators, air conditioners, and high-power equipment. All of these require 100A three phase energy meters for monitoring electricity consumption data and measuring energy consumption.
In a 100A energy meter, 100A is the max value of the current that can be measured by the energy meter. The min measurable current depends on the rated current of the energy meter, such as 0. 25~5(100), 0. 5~10(100) or 1~20(100) A. From the parameters of each current specification, we can see that in the standard requirements for energy meters, the 100A energy meter with a rated current of 5 A has a min accurate measurement current of 0. 25 A, while the 100A energy meter with a rated current of 10A has a min accurate measurement current of 0. The 5 A and 100A energy meters, with a rated current of 20A, have a min accurate measurement current of 1A. From the parameters, we can clearly see that the metering performance of the 100A energy meter with a rated current of 5 A is inferior to the other two models.
When selecting an energy meter, different users and application scenarios may have different requirements and specifications for the energy meter. Therefore, it is necessary to choose a suitable energy meter according to the actual situation.
