TM1 electric energy metering terminal is based on the industrial multi-function electric energy meter with wire / wireless network nodes, it is installed at the low voltage side of a transformer, 1140/660/380 voltage and current transformer is placed on the upper side of low voltage in let chopper switch, the converted signals are collected and calculated through the multi-function electric energy meter for storage and multi-function metering, and then they over transferred in real-time to the local network database through wireless network (GPRS/CDMA) or RS485 interface, and by using RF bluetooth, PDA Hand-writing unit is used for collecting and back playing the stored data to the database of local network, thus the full parameters of electric energy in the industrial system (Voltage, current, factice power and reactive power, power factors, electric energy, harmonic wane) are accurately collected.
