Application Scenario
(1)A typical building power system is a comprehensive system consisted of 3-phase & 1-phase power system. And 3-phase & 1-phase system are obviously consisted of the 3-phase & 1-phase circuits. And all the loads in this building are powered by all these circuits. Thus, the aim of Building Online Energy Monitoring for all the monitoring loads in a certain building was to first confirm and all the 3-phase & 1-phase circuits’ monitoroing point and deploy compatible energy meter and paired CTs if requested on them for energy monitoring. And then select compatbile IoT gateway or Wireless energy meter for data uploading to a Online IoT Energy Monitoring System. (2)The key of whether select the combination for IoT Gateway + Energy Meter or Wireless Energy Meter, was whether the energy meter could be of centralized installation or separate installation. This will decide which plan will be more economic and convinient to deploy.
Basic Solution Selection Logic
Three key factor will influence our solution on dicisiong of hardware module selection. •Type of monitoring circuit.
