The gateway meter independently developed by State Grid Information and Communication Industry Group has passed the 0.1-second level measurement accuracy test


The gateway meter independently developed by State Grid Information & Communication Industry Group Co., Ltd. passed the 0.1S level metrological accuracy test at Beijing Institute of Metrology and Testing Science. The test indicators include initial inherent error, self-heating, load imbalance, external magnetic field interference, harmonics in current and voltage circuits, etc. The test results show that the 0.1S level independently controllable gateway meter fully meets the requirements of the national metrological technical specifications for the type evaluation outline of installed AC energy meters, with a significant improvement in metrological accuracy.

  This test is a verification after upgrading the hardware design, metering algorithm, and software functions of the gateway meter based on the 0.2S level independently controllable gateway meter of State Grid Information & Communication Industry Group, marking another breakthrough in high-precision metering technology achieved by the group.
