The access impedance for Narrowband PLC communication is dependent of the global installation impedance. The interest of this paper is to measure the domestic installation impedance using a new setup based on an LCL filter for masking the network impedance. The short-time and the frequency variation of the global impedance in the frequency band between 30 and 500 kHz is measured in several scenarios. The domestic loads are classified according to their impact on the global installation impedance by connecting to the installation and changing the mode of operation. The access impedance is recalculated using the measured installation impedance in parallel to the network.
