摘要：NOVELTY - The system has a first analog-to digital converter module that is connected to microcontroller (MCU) module, current signal module, current mutual inductor and operational amplifier module. The voltage signal module is connected with the three phase power source. The current mutual inductor collects the high current signal to change to low current signal. The second analog-to digital converter module sends the direct current voltage effective value conversion to actual voltage value and current value of the three-phase power source. USE - Three-phase electric power monitoring system for electric appliance. ADVANTAGE - The electric power monitoring system reminds working personnel to implement power supply abnormal processing process, and performs storage and remote monitoring to detect state parameter of the three-phase power source. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for three-phase electric power monitoring method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of three-phase electric power monitoring system. (Drawing includes non-English language text)
