Overview
Specimen Track’s Three-Phase LoRaWAN Smart Energy Meter with Power Monitoring is a three-phase LoRaWAN electricity smart energy meter designed for single-phase two-wire, three-phase three-wire, or three-phase four-wire power grids. This device supports LoRa radio LoRaPMAC protocol, enabling communication over 2.4 to 4 km in unobstructed conditions with data transmission at 121 mA @ 22 dBm. It provides real-time monitoring of A/B/C three-phase voltage (L-N, L-L), current (Amp), kW, kVA, kvar, and power factor, including maximum, minimum, and average values. This device also features phase angle measurement, voltage phase sequence indicators, voltage and current asymmetry detection, selectable PT and CT ratios, THD up to the 41st order for voltage and current, and maximum demand measurements for Amp, kW, and kVA.
