DIY transformer, inductor and capacitor in-circuit ring tester DiodeGoneWild 2022-08-09 | Building a ring tester that can test transformers and inductors for short turns, even in a circuitboard. It can easily identify shorted windings, including just 1 short turn. Irreplaceable, especially when fixing switching power supplies and inverters, but also for vintage CRT television and monitor high voltage transformers and deflection coils. It's a simple ring tester, testing the winding based on the number of damped oscillations it can make with a resonant capacitor. 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. This tester can also ring test capacitors to estimate their dissipation factor.The previous episode:youtu.be/QBbEYYWiBI8The tester and program on my website:http://danyk.cz/avr_ring2_en.htmlPlease support me on Patreon:patreon.com/DiodeGoneWildMy Instagram:instagram.com/savage_danyk
