Abstract
When corona occurs at hardwire fittings or high voltage line, the surrounding gas will be ionized. As a result, the electromagnetic energy would release through light, audible noise, or other different ways. This paper analyzes the relationship between the photon numbers measured by ultraviolet imager (UVI) of different fittings and the audible noise. Analyses show that the A-weighted audible noise changes with the photon number exponentially. This exponential relationship is related to the kind of hardwire fittings with different exponential curve fittings coefficients. According to this exponential relationship, the number of photons of different hardwire fittings could be used ro calculate the A-weighted audible noise, or judge the contribution of one ionized hardwire fittings in the whole noise level of electric transmission line.
