Corona discharge is a common phenomenon in powertransmission lines external insulation, and it may cause serious defect if withouteffective detection. The ultraviolet UV imagery technology has been widely used todetect the corona discharge in industry in recent years, but some influencefactors’ functions are not definite. In this paper, the fracture aluminumstrands which is common in power transmission lines were used as the electrodemodel while a SuperB ultraviolet imager were utilized to detect, the photoncount rate was detected with different detect distance, electric field,aluminum strands length and UV gain were applied. Then the multivariateregression analysis MRA was taken to calculate the function between the photon countand the factors.
