Abstract :
In this paper, a real-time instrument for nonstationary disturbance measurement on power lines is reported. It is mainly based on a digital signal processor TMS320C6711 and on an original algorithm. In this paper, a full description of the realized instrument, which implements the proposed method for disturbance detection and extraction, is described in detail. This paper is completed with an experimental results comparison between a standard power line transient analyzer and the proposed one.
