Data process of ultraviolet counts for corona discharge detection based on data fusion technology

The corona is not a steady discharge because of the effect of detection conditions, so the data of ultraviolet(UV) counts is fluctuant. It is difficult to estimate the corona discharge with only one data or the average of several UV counts. To improve the precision and reliability of UV counts for corona discharge measurement, the authors use the methods of arithmetic average and batch estimation for processing the data of UV counts of corona discharge based on the principle of data fusion technology. As a result, the interference in the course of UV detection of corona discharge is suppressed to a certain extent, hence the detection result gets more accurate.
