The MOEORW-W6500 intelligent three-phase voltammeter (vector meter) is a handheld multi-functional measuring instrument specifically designed for the power industry. It is designed for the detection of power system protection circuits and metering circuits, as well as for the analysis of electrical parameters, and is a practical tool for power field operations.

This instrument integrates multiple functions such as phase verification, electrical parameter testing, metering wiring detection, harmonic analysis, and simple oscilloscope. It can complete the judgment of the correctness of the main transformer differential protection wiring, the analysis of three-phase three-wire metering wiring, the detection of harmonic content, and can also intuitively observe signal waveforms and analyze power quality. At the same time, it can calculate the primary side electrical parameters of the instrument transformer and accurately identify metering theft wiring methods.
