MULTI-GEM

Branch circuit power meter (Multi-GEM) offers reliable and accurate energy monitoring & management in real-time at electric multiple feeding points. The Multi-GEM automatically provides metering, demand, energy readings and loggings over multi feeding points with Multi-GEM 18 channel monitoring from the 18 feeders for 1P2W, 8 feeders for 3P3W, 6 feeders for 3P4W or any combination of single and three phase circuits. This useful exibility makes Multi-GEM be effective over IDC (Internet Data Center), of ce buildings and shopping malls and the other industries. Current detection of Multi-GEM is operated via external current transformers (CTs). Each CT measures 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 with- out wiring changes. The exible structure makes an easy energy consuming analysis and electric bill count for a valuable saving of time and money naturally.
