Power Quality (PQ) measurements for low voltage (LV) customers, domestic and business, have been carried out in order to detect the behaviour of the electric net over time and the quality of the electric energy being bought. In order to measure PQ parameters, we realized an instrument based on web server personal computers, which are common in office or in domestic environment. This allows us to conjugate the high PC calculus capability with the possibility to send data via internet to a central server; moreover, the use of the existing hardware infrastructure makes the instruments extremely cheap.
