摘　　要：总结了近年来多台次变压器现场局部放电试验的情况,分析了试验时容性无功容量的估算方法,通过与实际容量的对比,验证了估算方法的可行性。同时通过实例,分析了现场试验中典型干扰的抑制排除方法,展望了变压器局部放电技术的发展趋势。Through the analysis of the calculation method of capacitive reactive power in tests based on the summarization of the partial discharge tests of a great number of power transformers in recent years,the comparison with actual capacity is carried out and the feasibility of the calculation method is verified.Through the analysis of the elimination method of typical interference in field tests based on the cases,this paper points out the development trend of partial discharge technology of transformers.
