Product Introduction
MOEORW-WBC73 is a handheld high-performance transformer turns ratio tester designed for on-site power testing and factory inspection. Built with a three-phase sinusoidal inverter power supply and intelligent control system, it quickly measures turns ratio, connection group, polarity, angle difference, and excitation current fully automatically. It helps users detect turn-to-turn short circuits, open circuits, wrong wiring, and tap switch faults efficiently, ensuring transformer safety and compliance with IEC and national standards.
