中文摘要	A novel method is developed for measuring the performance of insulator corona by utilizing the photomultiplier (PMT) to detect the UV light. The experiment shows that the UV light pulses correspond very well with leakage discharge pulses, and the UV light can be used for monitoring the corona condition. When this method is applied to detect the corona of insulators, it is found that, for dry insulators, there exists only positive corona pulse on its corona discharge, while with the droplets on the surface of the insulators, negative pulses are also detected. Meantime, a program for automatic detecting of negative pulses is developed which can display the distribution of negative pulses. Experiments demonstrate that if water droplets exist on the surface of insulators, the negative corona pulses will be produced, which in turn demonstrate that the water droplets will intensify the negative corona and cause the accelerated increase of the amplitude of the negative pulse.
