内容記述 | Observations of the electromagnetic field strength of power line radiation over northern Europe were conducted under the geomagnetically active conditions using the balloons B_<15>-1N on March 20,1982 and B_<15>-2N on November 23 and 24,1982. Substorms occurred during the both flights. A substorm effect on the strength of the electromagnetic field of the power line radiation was investigated at the harmonic frequencies of commercial power line frequency, 50Hz in the frequency range from 40Hz to 1kHz. The strength of the power line radiation at the harmonics of 50Hz in the frequency range from 200 to 900 Hz enhanced during the substorms. A great increase of strength was observed at 300,450 and 600Hz on the balloon B_<15>-1N, and at 300,450Hz on B_<15>-2N. However, the strength at 50,100,and 150 Hz did not enhance more than 3dB during the substorms. It is concluded that the strength of the power line radiation enhanced at higher harmonics of 50Hz during a geomagnetic substorm. | |||||
