摘　　要：变压器局部放电的在线监测中 ,来自电网的干扰 ,如通信载波、各种放电脉冲等 ,以及这些干扰在相间串扰 ,在很大程度上影响着在线监测系统的灵敏度、可靠性。通过对在福建某水电厂BYT Ⅱ变压器局部放电在线监测系统的现场试验 ,测量了这些干扰 。The field interences coming form power system, such as communication noiseer pulse type noise and their couplings phase by phase inside the transformer will greatly influence the measurement sensitivity and reliability of . On line nonitoring partial discharges(PD) for power transformer. On line monitoring partial dischrges for power transformer by BYT Ⅱ, hose interfenences have been detected and corresponding anti interferece methods have been applied.
