Abstract

This paper describes the development of low cost embedded system for detecting and analysing the voltage sags in the ac supply. The proposed system have the capabilities of real time acquisition of voltage signal using an Embedded Controller and display its parameters in a Graphical User Interface in the Central Server (PC). The features of the signal are extracted using Discrete Wavelet Transform with Multi Resolution Analysis. The voltage sags are created in an experimental setup using voltage injection method. The real time voltages are sensed by Hall Effect Transducer and digitalised by mbed microcontroller (LPC1768 ARM Cortex-M3). The real time samples are then serially transmitted to the Central Server. A standalone application is developed in Central Server using Visual C Sharp for real time visualisation, processing and analysis of the signal.
