摘要

对于小于100 MVA的发电机来说，用于局部放电在线监测的仪器成为一个更昂贵的投资选择。对于这些机器，已经设想通过同时采用峰值检测和保持技术和已经嵌入微处理器或DSP(数字信号处理器)的固有模数(a /D)转换功能来实现部分放电测量的经济单位。这种技术被称为混合转换方案。

Hybrid conversion scheme for digital measurement of partial discharge spectra

An instrument for the online monitoring of partial discharges becomes a more expensive investment option for generators of less than 100 MVA. For those machines, an economic unit of partial discharge measurements has been envisaged by simultaneously adopting a peak-detect-and-hold technique and an inherent analogue-to-digital (A/D) conversion function already embedded in a microprocessor or DSP (digital signal processor). This technique is named as hybrid conversion scheme.
