    • Demagnetization of Current Transformers Using PWM Burden 

      Author: Bauer J.; Ripka P.; Draxler K.; Styblíková Renata
      (IEEE, 2015)
      Current transformers (CTs) show large errors when they are magnetized by dc current. This error can be reduced after proper demagnetization. One of the methods to demagnetize the CT is to increase the core flux by increasing ...
