HF radios often use toroidal transformers and winding them is a rite of passage for many RF hackers. [David Casler, KE0OG] received a question about how they work and answered it in a recent video … ...

Example based on a 350 MVA transformer. A 350 MVA-YNyn0 power transformer manufactured in 1971 and rated 400/30kV was tested. For verification of state purposes, SFRA measurements were conducted using ...

The transformer in the picture is a basic concept – 10 metal layers can easily fit inside 1mm FR4 stack – and high magnetic coupling 98% + transfer can be improved by adjusting the stack with ...

The WA 2293 is a winding analyzer that is optimized for testing three-phase power and distribution transformers. This test set uniquely combines winding resistance measurement, transformer turns ratio ...
