Single/three phase PLC electronic watt-hour meter is used in XJ Remote Centralized Meter Reading System as the system’s low side equipment to realize electric energy measuring, electric data power line carrier & communication function for individual user. The meter adopts special large-scale integrated circuit as its core element and has a few peripheral elements. It is of compact structure and high reliability, with the advantage of tamper-proof, high multiple overload, high accuracy, and strong communication capability.
The meter is based on power line carrier and communication technique. It uses LV power line as its communication channel. Its core technique is software technique and power frequency modularized technique. Consumed electric energy data can be transmitted to the remote centralized meter reading system of upper level in the mode of power line carrier style by using the mode identification and fuzzy processing technique.
