METHOD AND APPARATUS FOR DEMAGNETIZING TRANSFORMER CORES CLOSED-LOOP
摘要
Automated degaussing methods and apparatus are presented for degaussing a magnetic core in close loop fashion, in which a plurality of pulses are applied to a compensation coil magnetically coupled with the core with duration or energy being decreased in succeeding pulse cycles according to a discrete feedback algorithm, and with individual pulse polarities being set according to core magnetization polarity measured subsequent to an immediately preceding pulse.
