The Single Energy Meter Automatic Test Line is specially designed for automatic test of single – phase energy meters in mass production.
Applications:
· Electric power departments
· Electric energy meter manufacturers
· Measuring and quality examining departments
1) Accuracy: 0.1% , 0.05%
2) The breakdown of power source of MUT only affects one meter position unit, and the other positions still work normally, so the system is more reliable.
3) Each meter position unit with a power source and connect in parallel. The unit is totally separated, don't affect each other, eliminating the effect of large power output in stability of power source reducing error, and improving test accuracy.
4) The meter with different testing ranges, constants protocols can be tested together because each meter position unit are in parallel, which does not affect each other.
5) More meter position, less installation waiting time. Effective test time is shorter, only 30% of conventional test Methods.
6) Test single phase meter with closed link. Expansion of meter position units is easy and convenient.
7) Automatic meter loading /unloading and test, with PC control by Ethernet communication.
8) Flow of work: meter loading, indentation, location, testing, defect sorting, labeling, lead sealing, packaging, Return to meter's warehouse.
