Trackway Color Screen Power Quality Analyzer, designed for energy management and metering transformation needs of power systems, industrial and mining enterprises, public utilities, and intelligent buildings, is an intelligent instrument that utilizes a high-brightness color screen display. It operates through panel buttons for instrument operation and parameter setting, integrating the measurement of all power parameters (such as single-phase or three-phase current, voltage, active power, reactive power, apparent power, frequency, and power factor), and various power quality analysis parameters (THDu, THDi, voltage crest factor, telephone waveform factor, current K factor, voltage and current vector analysis, voltage and current unbalance analysis, etc.). It also features multiple peripheral interface functions for user selection, equipped with an RS485 communication interface using MODBUS-RTU protocol. It has 4G communication capabilities and uses MQTT protocol to meet communication and networking management requirements; with switch input and relay output, it can achieve the functions of "remote signal" and "remote control" for circuit breaker switches, making it highly suitable for real-time power monitoring systems.
