  • Transformer winding movement detection by high frequency internal response analysis
    Patent number: 6466034
    Abstract: Transformer winding movement is detected by providing an input sensor inside the transformer on an input winding lead and providing an output sensor inside the transformer on an output winding lead. This eliminates the frequency limitation imposed by the lead lengths required for prior art external measurement, making it possible to obtain useful measurements at much higher frequencies (20 MHz) than with the prior art techniques.
