Introduction: The project aims are to identify the high frequency voltage distortions caused by modern high power electronic equipment which may be installed in domestic premises, and to understand the propagation and attenuation of these effects on a real LV network installed at Imperial College London. It will also look at the impact of these distortions on customers’ equipment and produce information which will allow the calculation of these effects on large LV networks. Ten energy and micro-generator manager (EMMA) units which can handle 3kW each are to be studied on a small network at Imperial College London, comprising 100 metres of mains cable and 16 services arranged to allow balanced and unbalanced loading conditions to be studied.

Objectives: The use of high-powered electronic devices in domestic premises and potential interference with other equipment. Also the effect of high penetrations of these devices.
