The webinar provides information about the influence of remanent magnetism in power transformers. It addresses causes of this phenomenon, such as winding DC resistance testing and a consequence of the remanent flux. The remanent magnetism can cause various problems such as erroneous measurements on a transformer, an increased inrush current at the start-up of transformers, or incorrect operation of protective relays. Webinar provides the information about the process and different methods of performing demagnetization, detection and verification of the demagnetization process. Also, available test devices with demagnetization features are presented.
The webinar will be held in the English language.
