研究目的
Investigating the effect of different step responses on the corrected impulses measured with ultra-high-voltage dividers.
研究成果
Different arrangements for step response measurement resulted in significantly different values of response parameters. However, accurate corrections for lightning impulse waveforms measured by dividers in the UHV range were achieved without being compromised by the connection arrangement of the step response measurement.
研究不足
The study focused on the effect of step response measurement arrangements on the correction of lightning impulses but did not explore the frequency analysis of the step response in detail.
1：Experimental Design and Method Selection:
The study used two circuit arrangements for step response measurement to investigate their effect on corrected impulse waveforms. The step responses were measured using a square arrangement and a triangular arrangement as recommended in IEC 60060-2:
2：Sample Selection and Data Sources:
20 Two different 2400 kV lightning impulse dividers were used, one with a commercial low voltage arm (LV1) and another with a better matched low voltage arm (LV2).
3：2). List of Experimental Equipment and Materials:
3. List of Experimental Equipment and Materials: A step generator with an output step voltage of 500 V and a rise time of 3 ns was used for step response measurement.
4：Experimental Procedures and Operational Workflow:
The step responses were measured with both arrangements and used to correct the lightning impulses measured with the dividers. The corrected waveforms were compared with those measured by a reference divider.
5：Data Analysis Methods:
The errors of the impulse parameters before and after correction were determined and compared.
