Dc Resistance of Transformer T101 The dc resistances of the transformer windings should be checked when the sc voltage readings vary from those shown in figures 42, 43, and . Resistance measurements are taken to locate shorts between windings, shorts to ground, open windings, and high resistance connetions. The dc resistances of the transformer windings will vary widely with each manufacturers design and should not be the determining factor for re- replacement. Typical measurements taken from three different Test Sets, Electron Tube TV-7 ()/ U are shown in the following chart: Page 39, paragraph 22.
