WXMG3000B Three-Phase Intelligent Phase and Volt-Ammeter
Belongs to category： Intelligent Phase and Volt-Ammeter
Introduction
The WXMG3000B Three-Phase Intelligent Phase and Volt-Ammeter is a versatile smart meter specifically designed for on-site testing. It consists of a main unit, current clamps (3), test leads (4), and other components. The main unit features a 3.5-inch true-color LCD screen with a graphical menu interface and phasor diagram display, making readings clear and intuitive. The current clamps are designed with compact, narrow jaws for easy operation, making them highly suitable for use in areas with densely arranged wires.
The WXMG3000B allows for simultaneous measurement of various three-phase AC parameters without breaking the circuit under test. Its capabilities include measuring voltage, current, phase angles between voltages, between currents, and between voltage and current, frequency, phase sequence, active power, reactive power, apparent power, power factor, and current vector sum. It can be used to identify transformer connection groups, determine if a circuit is inductive or capacitive, test secondary circuits and busbar differential protection systems, read the phase relationships between CTs in differential protection groups, check the correctness of watt-hour meter wiring, and troubleshoot line equipment. It provides a safe, accurate, and convenient intelligent instrument for electricity inspection personnel. It is suitable for applications in electric power, petrochemicals, metallurgy, railways, meteorology, industrial and mining enterprises, research institutes, universities, and metrology departments. It is particularly well-suited for use in electricity billing systems and relay protection systems.
