Product Introduction
MOEORW-W4610A21 is a high-speed, high-precision DC resistance tester for transformer winding fault detection. It helps you quickly find virtual welding, strand breakage, inter-turn short circuit, poor tap switch contact and other hidden dangers. With automatic discharge, sound alarm and mobile APP control, it greatly improves safety and efficiency for factory test, handover test, overhaul and preventive test.
