Transformer winding resistance can help you determine the condition of transformers. When a transformer develops defects like coil to core or coil to coil shorts, opens and corroded connectors, the resistance of the windings change. It is a good idea to regularly test transformer components because a defect can cause severe power losses, electrical instability and eventual failure.
