Total kWh energy consumption of a building depends on the entire usage of distinctive electrical equipment in that building. To determine the contribution of these electrical equipments to the total energy consumption is difficult and may require kWh meter to be installed in each of them. This paper presents Non-intrusive Load Monitoring (NILM) method to trace energy consumption of different electrical equipment by using the harmonics current originated from the equipments as their signature. The potential and feasibility of the method is tested through laboratory experiment. Three different set of electrical equipments being used i.e. Personal Computer (PC), fluorescent lamp (T5 type) and compact fluorescent lamp (CFL). The experimental results show the potential of the method to do the tracing.
