750kV交接试验规程中变压器长时感应电压带局部放电试验各电压规定解读

Interpretation of Regulations of Voltages in Long-Duration Induced AC Voltage Withstand Test with Partial Discharge Test of Transformer in 750k V Hand-over Procedures

本文通过对110~1000k V变压器交流绝缘水平与长时感应电压（ACLD）带局放放电试验各电压的关联系数进行分析,比对2007版750k V交接规程和2013版的各电压规定,最终得出2013版750k V交接规程中ACLD各电压的规定是科学合理的。

Correlation coefficient between AC insulation level of 110~1000k V transformer and voltage of Long-Duration Induced AC Voltage Withstand Test（ACLD） with partial discharge test is anaylyzed. Compared with regulations of voltages in 2007 and 2013 version of 750 k V hand-over procedures, scientific rationality of the regulations of ACLD votages is proved.
