摘要

目前在绝缘诊断中广泛采用趋势技术在线监测方案。本文介绍了两种用于绝缘诊断的在线监测仪器。第一个单元在选定的频段内获得局部放电幅度和动态滞止电压等参数。这些技术可以更精确地解释局部放电活动。第二种是低成本、低时间分辨率的局部放电光谱。介绍了几种局部放电在线监测传感器。

Novel on-line partial discharge monitoring system for generator/motor stator insulations

Nowadays on-line monitoring scheme with trending technique is widely adopted in insulation diagnosis. In this paper, two types of online monitoring instrumentation for an insulation diagnosis are proposed. The first unit obtains the parameters such as partial discharge magnitude and dynamic stagnation voltage (DSV) in selected frequency bands. The partial discharge activities can be interpreted more precisely by these techniques. The second one indicates the partial discharge spectra in reduced time resolution with lower cost. Several online sensors for partial discharges monitoring are also introduced.
