The handheld winding ohmmeter RMO-TH device is DV Power single-phase instrument specially designed for measuring transformer winding resistance and performing transformer demagnetization. Winding resistance is determined by injecting DC current through a winding, accurately measuring DC voltage across the winding, and then calculating resistance as the ratio of voltage and current. The device generates true DC ripple-free currents. Both the injection of the current and the discharge of energy from the transformer magnetic circuit are automatically regulated.
