Electromagnetic emission of a hollow needle to mesh negative corona and quasi-periodical spark discharge in the air
Original language description
We investigated the emission of electromagnetic waves from the stainless-steel hollow needle to mesh corona and quasi-periodical spark discharge without and with airflow through the negative needle electrode in the frequency range below 500 MHz. We showed that there is no electromagnetic waves emission from the pulseless corona discharge. After the discharge transition to the quasi-periodical spark, high-amplitude current pulses correlate with the bursts of electromagnetic radiation. We demonstrated that the spectral distribution of emitted radiation is independent of the discharge voltage, current, and airflow through the needle electrode. We found that the highest peak of the power level of the electric component of emitted waves occurs at the frequency of 15.2 MHz, and the power level of emitted radiation as a function of frequency gradually decreases.
