The paper deals with the problem of estimating net harmonic currents injected by groups of non linear appliances present within typical domestic customers mix. To this aim a simulation based on "bottom-up" approach for accounting the cancellation phenomena among individual contributions hs been adopted and extended. The non linear appliances considered are Television set, Personal Computer, Fluorescent and Compact Fluorescent Lamp. The simulation operation of linear load has been taken into due account in order to simulate more closely real-life conditions. The simulation results are organised in tables which provide the estimate of main net harmonic currents (31th, 5th and 7th) likely to be monitored at the low voltage busbars supplying an end-use area composed exclusively by domestic customers. The validity of the methodology proposed has been tested by comparing simulation results with some field measurements from a raidentidl area investigated.
