A SMART POWER QUALITY SENSOR FOR THE EVALUATION OF FLICKER EFFECT

• Abstract:

  The monitoring of power quality (PQ) on supply networks is today an issue of worldwide interest. In this field, one of the most important parameter is the flicker effect, a phenomenon due to luminance fluctuations of the lighting caused by voltage variations. The IEC standardized the implementation of a flickermeter, to supply information about the human reaction to the voltage amplitude modulation. Starting from a different flicker measurement approach proposed by the authors, in this paper a low-cost smart flicker sensor has been designed and applied. The proposed sensor can transmit data over a TCP-IP network, in order to allow for a remote monitoring of power quality. The performance of the proposed device has been compared with a standard flickermeter and the main experiment results reported.
