Response Test of Power Transformer Windings Excited by Nanosecond Pulse
At present, the detection of transformer winding deformation in the offline phase, in order to discover the small transformer winding deformation, realize the online monitoring, in this paper, using nanosecond pulse frequency response analysis method, the detection of transformer winding deformation is studied, the results show that the nanosecond pulse frequency response analysis method in the detection of transformer winding deformation with high reliability and sensitivity.In order to verify the repeatability of the method, the method was used again at a 30-day interval under the condition that the detection environment was basically unchanged. The ρ value was 0.9719 in the range of 1 kHz∼1 MHz.
