摘要：

As the increasing voltage grade of power electrical equipment, on-line monitoring and. diagnostic of the power transformer's insulation have become one of the most important studies in high voltage research. At the same time, lots of researches have shown that the insulation aging has direct relationship with the partial discharge (PD) activities. A new instrument, which based on AVR, is introduced to measure the characteristics of PD in large power transformers accurately. In addition, it can also be used to on-line monitoring of the PD activities under high field conditions.
