Shorted transformer hard to tell? Let's build a tester of transformers and inductors. It can identify shorted windings, including just 1 short turn. It's hard to test switching transformers and inductors for internal shorts using any other tool. This tool is very useful, especially when fixing switching power supplies and inverters. It's a simple ring tester, testing the winding based on the number of damped oscillations it can make. An internal short will turn a high Q factor transformer or inductor into a very low Q one, resulting in way less damped oscillations (rings). The Q factor is affected by the internal short turns way more than the inductance is.
