| Abstract: | In order to study the radiated noise caused by an electrical fast transient/burst(EFT/B) in a mine,its frequency-spectrum characteristics are analyzed.The measured frequency of spectrum analyzer is in the range of 3MHz~1GHz,and the method of field test is investigated.The results showed that the effect of EFT/B upon the electromagnetic radiated the environment in mine tunnel remained very limited,and the radiated emission energy of intrinsic-safe electronic equipment also limited.It is shown that the radiat... |
