40A Winding Resistance Tester

40A Winding Resistance Tester

The HVEX 40 A Ohmmeter Case is a versatile solution for measuring the ohmic resistance of windings such as coils, reactors, and transformers. Once a resistance range is established for the type and class of the equipment being tested, a divergent measurement can indicate issues such as insulation failure, a short circuit between turns, or a partial break with insufficient conduction. This facilitates the identification of problems and highlights the need for maintenance, whether preventive or corrective. Keywords: ohmmeter, resistance, coil, winding, inductor, reactor, transformer, measurement, maintenance
