Wireless Green Energy Meter(Wi-GEM) adopts Zigbee solution for a wireless telecommunication. It is used for industrial application like factory, building automation and SCADA as well. Wi-GEM is cosisted of EMU(Energy Meter Unit), EMR(Energy Meter Router), EMC(Energy Meter Coordinator) and iSAST OPEN CTs such as split CTs or �exible Rogowski coils by customer need. Customer can choose their power lines from single phase to 3P3W / 3P4W for metering. It measures power energy consumption e�ectively in real time. User can set up time to collect data. After installation of one EMU, it sends data to EMR in each �oor as wireless way then EMR sends data to EMC. Finally EMC talks to computer. Installation is simple and easy without any disconnection of live power line as well as the compact design and easy modbus open protocal support.

WIRELESSGREEN ENERGY METER
Electric power energy meter(EMU) performs variable electric measurements with pre-wired split core current transformers(CTs) and the voltage input and send the data to EMR or EMC automatically. EMU is applied to both single or three phase line with a wireless(radio) communication.
Energy Meter UnitRouter (Repeater), EMR extends the transmission distance between the Meter (EMU) and the Coordinator (EMC) to get a smooth transmission.
Energy Meter RouterStand alone gateway, EMC manages the wireless network and collect the data periodically sent by the Wireless EMU or EMR. The Meter Coordinator (EMC) can be accessed by the data logging system for metering and the other analysis use.

GENERAL FEATURES
Multi Green Energy Meter(Multi-GEM) is the reliable and accurate energy management and metering device under real time monitoring at electric multiple feeding points. The Multi-GEM automatically provides metering, demand, energy readings and loggings over multi feeding points Multi-GEM_18 monitors up to 8x3phase circuits or 18 single phase circuits or any combination of single and three phase circuits. This useful �exibility makes Multi-GEM be e�ective over IDC (Internet Data Center), o�ce buildings and shopping mall and the other industries. Current detection of Multi-GEM is operated via external current transformers(CTs), Each CT measurement and log the current and energy with the voltage input consumed by each of the branch circuits at the electric feeding points. This �exibility allows simple restructuring for electric circuit group without wiring changes. The �exible structure makes an easy energy consuming analysis and electric bill count for a valuable saving of time and money naturally.
