To reduce power consumption or carbon emission, detailed power measurement for 
each process, line, and device is required.   
By installing Wi-GEM, detailed power measurement is enabled. Wi-GEM also can 
perform the following: 
 
Measurement of voltage, current, active/reactive power, apparent power, 
power factor, and frequency 
 
Measurement of peak power 
 
Simultaneous event monitoring and storing for instantaneous low-voltage and 
over-current 
 
Measurement of 21 harmonic data (voltage and current) for each phase 
 
Because we open the Modbus protocol and register map for measurement, you can 
easily build your own system.
