YANG Jin-chun, ZHOU Jian-fei, LV Jian-hong, et al. Application of sound intensity method in sound power level measure of power transformer[J]. 2012, 32(2): 9-11.DOI:
The sound power level of power transformer is the main parameter for prediction or evaluation of noise influence of substation.Sound intensity method is superior to the traditional methods including sound pressure and sound power measurement methods.It is not easiily affected by sorrounding environment and can measure the sound power level of the transformer station outdoors conveniently and accurately.
