Development of advanced technology for high voltage transformer winding condition control based on probing impulse of nanosecond duration

open access: yes, 2018
The paper deals with the experimental research of the pulsed method of transformer winding control in comparison with FRA technology. A new approach to winding condition control technology is described. The proposed method is based on short (compared with a typical pulsed technology) probe pulse and front pulse durations.
